Question

Diamond has a density of 3.26 g/cm3. What is the mass of a diamond that has a volume of 0.276 cm3?

Answer 1

For every 1 cm^3, you have 3.26 g. Because of this, you can just multiply the amount of cm^3 you have by the grams per cm^3, which is 3.26 g.

3.26 x .276 cm^3 = .89976 g or .900 g adjusted to significant figures
