Question

0.05 kg of penicillin G was dissolved in saline solution and brought to a volume of 1 liter. What is the concentration of the solution in milligrams of Penicillin G per ml of solution? (Show your work. Use conversion factors.)

Answer 1

$$1 L = 1000ml$$

$$0/05kg = 50g = 50000mg$$

$$w_{mg/ml} = 50000mg/1000ml = 50mg/ml$$
