A sample of sand has a mass of $51\mathrm{.}9g$ and a volume of $26\mathrm{.}7c{m}^3.$ Calculate its density in grams per cubic centimeter $(\frac{g}{c}{m}^3).$

density:

Acetone, the solvent in many nail polish removers, has a density of $0\mathrm{.}791\frac{g}{m}L.$ Calculate the volume, in milliliters, of $19\mathrm{.}7g$

of acetone.
