Question

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

Short answer

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.

$Masspercent(m/v)=\frac{solutemass}{solutionvolume}\times 100\%$

The problem,

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

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

$=0.005g$

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

Explanation.

So,

$Solutionvolume=\frac{solutemass}{Masspercent(m/v)}\times 100\%$

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

$=0.2mL$

The amount of compazine standard solutions required is $0.2mL.$
