Amoxicillin 2 mL corresponds to how many mg, given a 125 mg/5 mL concentration?

Understanding drug concentration and volume helps with proportional dose calculations. If a preparation is 125 mg in 5 mL, the concentration is 125 mg ÷ 5 mL = 25 mg per 1 mL. For 2 mL, multiply 25 mg/mL by 2 mL to get 50 mg. So the amount in 2 mL is 50 mg. (25 mg would be in 1 mL, 100 mg in 4 mL, 125 mg in 5 mL.)
