Question

Osmium is a chemical element with a density of 22.6 grams per cubic centimeter. A piece of Osmium has a volume of 15.1 cubic centimeters. What is the mass of the piece of Osmium to the nearest tenth of a gram?

Answer 1

341.3 g

Explanation:

we know that

The density is equal to the ratio of the mass by the volume

D=m/V

Solve for the mass m

m=D*V

In this problem we have

D=22.6 g/cm³

V=15.1 cm³

substitute in the formula

m=22.6*(15.1)=341.26 g

Round to the nearest tenth of a gram

341.26 g=341.3 g
