Answer:
The total mass of insulin is 15,750mg.
Explanation:
The total mass of insulin can be calculated by the following formulae:
[tex]concentration=\frac{mass}{volume}[/tex]
Here, concentration=30.0mg/ ml and volume is 525ml.
[tex]30=\frac{mass}{525}[/tex]
[tex]mass= 525\times 30[/tex]
=15,750 mg
Thus, the mass of insulin in the bottle is 15,750mg.
