A doctor orders 0,075 g of chlorpromazine, which is used to treat schizophrenia. If the stock solution is 2,5% (m/v), how many milliliters are administered?

Answer 1

2.5% (m/v) means it is 2.5 grams drug / 100 ml of solution = 0.025 g drug/ml solution

(x ml)(0.025 g/ml) = 0.075 g

x = 0.075 / 0.025

x = 3 mls
