11 5 pts The density of copper is 896 gem3 What is the mass

11. (5 pts) The density of copper is 8.96 g/em3. What is the mass in of a cube of copper that measures 2.13 mm on each side? (Show All Work!)

Solution

Volume of cube = a^3 here a= 2.13 mm = 0.213 cm

volume of cube = 0.213^3 = 9.66*10^-3 cm^3

now

mass of cube = volume of cube*density of cube

= 9.66*10^-3 cm^3 *8.96 g/cm^3= 0.08658 grams
