Chapter 9: Q. 9.74 (page 314)

Michelle's doctor orders $5.0 m g$ of Compazine, which is used to treat vertigo. If the stock solution is $2.5 % (m / v)$ , how many milliliters are administered?

Short Answer

Expert verified

The quantity of compazine known concentration required is 0.2 mL.

Step by step solution

Introduction.

Adults frequently suffer vertigo and disorientation during visits to their doctors.

Given data.

Using the following expression, determine the mass by volume percent.

$M a s s p e r c e n t (m / v) = \frac{s o l u t e m a s s}{s o l u t i o n v o l u m e} \times 100 %$

The problem,

Michelle's doctor prescribed a large amount of compazine to treat her vertigo.

$= 5.0 m g \times \frac{1 g}{1000 m g}$

$= 0.005 g$

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

Explanation.

So,

$S o l u t i o n v o l u m e = \frac{s o l u t e m a s s}{M a s s p e r c e n t (m / v)} \times 100 %$

$= \frac{= 0.005 g}{2.5 %} \times 100 %$

$= 0.2 m L$

The amount of compazine standard solutions required is $0.2 m L .$
