The premixed nitroglycerin solution contains 50 mg in 250 mL. What is the concentration in mg/mL?

Concentration is determined by how much drug is present per unit of volume. To find mg per mL, divide the total amount of drug by the total volume. Here, 50 mg in 250 mL gives 50 ÷ 250 = 0.2 mg/mL. A quick check: 0.2 mg for every 1 mL means 5 mL would contain 1 mg, which aligns with the given ratio. The concentration is 0.2 mg/mL.
