A substance with a density of 2.70 g/mL occupies a volume of 21.3 mL. What is the mass of the sample? Report your answer in units of mg. Use significant figures. Do not enter “mg” as part of your answer. Do not use scientific notation.

We know the formula of the density:
ρ =[tex] \frac{m}{V} [/tex] ;
So the mass will be equal to:
m = ρ * V = 2.70  * 21.3 = 57,51 g = 57510 mg of substance.
So the answer is 57510.
