Question

Insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. A bottle contains 275 mL of insulin at a concentration of 50.0 mg/mL . What is the total mass of insulin in the bottle?

Answer 1

Answer: 13750mg or 13.75gram

In this case, the insulin has 50mg/ml concentration with 275ml volume. To know the mass, you need to multiply concentration with volume. The calculation would be

mass= concentration x volume
mass= 50mg/ml x 275ml= 13750mg or 13.75gram
