Question

insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. A bottle contains 325 mL of insulin at a concentration of 20.0 mg/mL . What is the total mass of insulin in the bottle?

Answer 1

The total mass of insulin in the bottle is 6500 mg

Step-by-step explanation:

The formula of concentration is:

`Concentration =(mass)/(volume)`

Clearing out the mass we have:

Mass = concentration x volume

Replacing the values:

Mass = (20.0 mg/mL) (325 mL) = 6500 mg

Note that the units are cancelled.

So, there are 6500 mg or 6.5 g of insulin in the bottle

Answer 2

To determine the total mass of insulin in the bottle, we simply need to multiply the volume of the contents to the concentration of the insulin. We cancel the volume units, then get the total mass with units of mg.

mass of insulin = 35 mL ( 20.0 mg / mL ) = 700 mg insulin

Hope this answers the question. Have a nice day.
