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 40.0 mg/mL. what is the total mass of insulin in the bottle?
40mg for every mL so you take 40x325 to wind up with 13,000mg of insulin or 13 grams.
Answer: The bottle has a total mass of 13000 mg of insulin.
Explanation:
We are given:
Concentration of insulin = 40 mg/mL
and we need to fins the mass of insulin in 325 mL of bottle.
From above, we know that:
1 mL contains 40 mili-grams of insulin.
So, 325 mL will contain = \(\frac{40}{1}\times 325\) = 13000 mili-grams of insulin.
Hence, the bottle has a total mass of 13000 mg of insulin.
