Question

A bottle contains 475 ml of insulin at a concentration of 40.0 mg/mL. What is the total mass of insulin in the bottle?

Answer 1

Answer:- 19 gram.

Solution:- From given information, the bottle contains 475 mL of insulin. The concentration of this insulin is 40.0 mg per mL. It asks to calculate the mass of insulin present in this bottle.

We could do this using dimension analysis which is very easy. In simple words, the concentration is multiplied by the volume to get the mg of insulin. the set up looks as:

`475mL((40.0mg Insulin)/(1mL))`

= 19000 mg of insulin

So, 19000 mg or 19 g of insulin are present in the bottle.
