You need to design a bronze bearing with a mass of 2 grams and
a volume of 0.230 cm3. The density of copper is 8.94 g/cm3 that of tin is 7.27 g/cm3.
1)What will the density be of the bronze?
2) What composition should the bronze have (that is, what percent by
weight should be copper and what percent tin)?

    The mass unit associated with density is usually grams. If the volume (in mL or cm3) is multiplied by the density (g/mL or g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 2.00 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3
