Question

Insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. A bottle contains 475 mL of insulin at a concentration of 30.0 mg/mL . What is the total mass of insulin in the bottle?

Answer 1

Knowing that:
C = Common concentration
m = Mass of the solute
V = Volume of solution

Data:

C = 30 mg/mL
m = ?
v = 475 mL

Formula:


`C = (m)/(v)`

Solving:


`C = (m)/(v)`

`30\:mg/\diagup\!\!\!\!m\diagup\!\!\!\!L = (m)/(475\:\diagup\!\!\!\!m\diagup\!\!\!\!L)`

`m = 30*475`

`\boxed{m= 14250\:mg}or\:\boxed{m\approx14.25\:g}\end{array}}\qquad\quad\checkmark`

Answer:

`\underline{the\:total\:mass\:of\:insulin\:in\:the\:bottle\:is\:14.25\:grams}`
