The proper dosage of a certain medication is 0.50 mg per kilogramof of patient weight. The medication is the Spence in a liquid that contains 350.0ug of medication per mL of liquid. What volume of liquid medication should be given to a 183 Ib patient. (1kg= 2.204 lb)

Answers

Answer:

118.61 mL.

Explanation:

Hello!

In this case, since we know the concentration in the medication:

[tex]\frac{350.0\mu g}{1mL}[/tex]

Now, since there are 0.50 mg of the medication per kilogram of patient, we can compute the volume as shown below for a 183-lb patient:

[tex]183lb*\frac{1kg}{2.204lb}* \frac{0.50mg}{1kg} *\frac{1000\mu g}{1mg} *\frac{1mL}{350.0\mu g} =118.61mL[/tex]

The question is incomplete, the complete question is;

Suppose 1.87g of nickel(II) bromide is dissolved in 200.mL of a 52.0mM aqueous solution of potassium carbonate. Calculate the final molarity of nickel(II) cation in the solution. You can assume the volume of the solution doesn't change when the nickel(II) bromide is dissolved in it. Be sure your answer has the correct number of significant digits. The answer is needed in M.

Answer:

0.0428 M

Explanation:

The equation of the reaction is;

NiBr2 + K2CO3 → NiCO3 + 2KBr

Number of moles of NiBr2 = mass/molar mass = 1.87 g/218.53 g/mol =

8.557 *  10^-3 moles

Now, we know that the Ni^2+ comes from the NiBr2. Also, the concentration of Ni^2+ in NiBr2 = concentration of Ni^2+ in NiCO3

So,

Concentration of Ni^2+ = 8.557 *  10^-3 moles/0.2 L = 0.0428 M

Select the BEST definition for entropy. Select one: a. stored energy in a substance that is exchanged as heat during a reaction (at constant pressure). b. tendency for a substance to achieve maximum disorder (i.e., randomly distribute). c. state of balance between a forward and a reverse reaction. d. ability of an atom to attract electrons for bonding.

Answers

Answer:

b. tendency for a substance to achieve maximum disorder (i.e., randomly distribute).

Explanation:

Entropy can be defined as the tendency for a substance to achieve maximum disorder (i.e., randomly distribute).

This ultimately implies that, entropy is a thermodynamic quantity that measures the degree of maximum order or randomness of a system.

The S.I unit used for the measurement of the degree of maximum order or randomness of a system is Joules per Kelvin (JK¯¹). An example of entropy is the mixing of ideal gases.

g A and B are both non-volatile molecular compounds. Substance A has a greater molar mass than substance B. If 50 g of substance A are dissolved in 250 g of water in one beaker, and 50 g of substance B are dissolved in 250 g of water in another beaker, then which ONE statement below will be true? A) the vapor pressure of solution A will be lower than the vapor pressure of solution B. B) the solution of A will freeze at a lower temperature than the solution of B. C) the two solutions will have the same vapor pressure. D) the boiling point of solution A will be lower than the boiling point of solution B. E) the solution of A will have a higher osmotic pressure than the solution of B.

Answers

Answer:

The correct answer is - option D.  the boiling point of solution A will be lower than the boiling point of solution B

Explanation:

Colligative properties such as a decrease in the freezing point of the solution, increase in the boiling point of substance, decrease in Lowering of vapor pressure, and other properties depend upon the number of molecules only.

In the given solution the equal amount of two solutions are mixed that is 50 grams however due to the difference in the molecular mass so the atoms present in both solution A and B will be different. It is known that the number of atoms of a substance is inversely proportional to the molecular mass of the particular substance.

As it is given that Solution B has a low molecular mass which means it has a high number of atoms that means its boiling point will be higher than solution A.

A solution is prepared by dissolving 10.6 g sodium carbonate in enough water to produce
500.0 mL solution. What is the molarity of sodium carbonate in the solution?

Answers

Answer:

0.2mol/dm³

Explanation:

Given parameters:

Mass of Na₂CO₃   = 10.6g

Volume of solution  = 500mL

Unknown:

Molarity of solution  = ?

Solution:

The molarity of a solution can be determined using the expression below:

 Molarity = [tex]\frac{number of moles }{volume}[/tex]  

     Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

Molar mass of Na₂CO₃ = 2(23) + 12 + 3(16)  = 106g/mol

   Number of moles  = [tex]\frac{10.6}{106}[/tex]   = 0.1mol

   Convert mL to dm³;

        500mL will give 500 x 10⁻³dm³or 0.5dm³  

So;

Molarity  = [tex]\frac{0.1}{0.5}[/tex]    = 0.2mol/dm³

In a heterogeneous chemical reaction requiring the use of a solid catalyst, the rate of the reaction could not be increased by increasing the concentration of reactants, but was doubled by doubling the amount of solid catalyst added. This probably indicated that

Answers

Answer:

The active sites on the initial amount of catalyst were fully saturated

Explanation:

A catalyst is a substance which alters the rate of a chemical reaction but largely remains unaltered at the end of the reaction. A catalyst has an active site which enables it to catalyze a reaction.

The active site provides the best possible orientation for reactant molecules to collide in order to form products.

When the active sites are not fully saturated with reactant molecules, more reactant molecules can bind and the reaction can proceed much faster. However, if the active sites of the catalysts are fully saturated, the reaction has maximum velocity and cannot go anymore faster.

Addition of more catalyst molecules can however make the reaction proceed faster as a it provides more active sites for reaction for the reactants.

After looking at the schematics of the bubble, he finds that it holds 0.750 moles of gas at Standard Temperature and Pressure. Unfortunately for Rooster, helium gas is not sold by the mole, only by the liter. He needs to know how many liters of gas 0.750 moles of helium is.

Answers

Answer:

16.8 L

Explanation:

From the question given above, the following data were obtained:

Number of mole of He = 0.750 mole

Volume of He =?

Recall:

1 mole of any gas occupy 22.4 L at STP. This also implies that 1 mole of He occupies 22.4 L at STP.

Finally, we shall determine the volume occupied by 0.750 mole of He. This can be obtained as follow:

1 mole of He occupied 22.4 L at STP.

Therefore, 0.750 mole of He will occupy = 0.750 × 22.4 = 16.8 L at STP.

Thus, 0.750 mole of He is equivalent to 16.8 L

Calculate the molality of an ethylene glycol (C2H6O2) soltuion, that has a molarity of 2.07 M. The density of the solution is 1.02 g/mL. Only enter the numerical value with 3 significant figures in the answer box below. Do NOT type in the unit (m).

Answers

Answer:

2.03

Explanation:

Let's assume we have 1 L of the solution:

There would be 2.07 ethylene glycol moles.The solution would weigh (1000 mL * 1.02 g/mL) = 1020 g.

With that information we can calculate the molality:

molality = moles of solute / kg of solventmolality = 2.07 moles / (1020 ÷ 1000) = 2.03 m

Keep in mind that this is only an estimate, as we used the kg of the solution and not of the solvent.

The molality of an ethylene glycol solution is 2.03 kg.

What is molality?

The moles of solute divided by the mass of solvent in kilograms is known as the molality of a solution.

Calculation of molality:

Given that, molarity is 2.07 M

Density is 1.02 g/ml

Step 1: To convert  the litre into grams, multiply the quantity by 1000

The weight of the solution is [tex]\bold{1.02 \;g/ml\; \times 1000 = 1020 g}[/tex]

Now, molality = moles of solute is divided by mass of solvent in kilograms.

[tex]\bold{Molality = 2.07 \times \dfrac{1020}{1000} = 2.03\; kg}[/tex]

Thus, the molality of the solution is 2.03 kg
