Q. 9.73 - An Introduction to General, Organic, and Biological Chemistry

Question

After her latest dialysis treatment, Michelle experienced vertigo and nausea. Michelle's doctor orders $0.075 g$ of chlorpromazine, which is used to treat nausea. If the stock solution is $2.5\% (m/v)$, how many milliliters are administered?

Step-by-Step Solution

Answer

So $3 mL$ of chlorpromazine stock solution is required.

Step 1: Introduction.

Hemodialysis is a therapy for persons with failing kidneys. Your kidneys do not filter blood to circulate when you have organ failure.

Step 2: Given Data.

Using the following expression, calculate the mass by volume fraction.

$Mass percent (m/v)=\frac{solute mass}{solution volume}\times 100\%$

Given,

Michelle's doctor prescribed $0.075 g$ of chlorpromazine to address her nausea.

The stock solution's mass/volume percent is $2.5\% (m/v)$.

Step 3: Explanation.

So,

$Solution volume=\frac{solute mass}{mass percent (m/v)}\times 100\%$

$=\frac{0.075 g}{2.5\%}\times 100\%$

$=3 mL$

As a result, $3 mL$ of chlorpromazine standard solutions is required.
