Question

After her latest dialysis treatment, Michelle experienced vertigo and nausea. Michelle's doctor orders 0.083 g of chlorpromazine, which is used to treat nausea. If the stock solution is 3.2 % (m/v), how many milliliters are administered?

Answer 1

Answer: 2.6 ml of chlorpromazine are administered.

Explanation:

Given stock solution of chlorpromazine, 3.2 %(m/v) i.e 3.2 grams of  chlorpromazine are dissolved in 100 ml of solution

We need to find the volume of solution that can contain 0.083 grams of chlorpromazine.

By applying unitary method, we get:

3.2 grams of chlorpromazine is present in 100 mL of solution.

So, 0.083 grams of chlorpromazine will be present in = $\frac{100mL}{3.2g}\times 0.083=2.6mL$ of solution.

Hence, the given amount of chlorpromazine will be present in 2.6 mL of solution and thus 2.6 ml are administered.
