If the density of copper is 8.96 g/cm^3, and if the density of benzene is 0.8786 g/cm^3, what mass of copper will have the same volume as 15 grams of benzene? Express your answer in grams
:
let x = the weight of copper
An inverse relationship
=
Cross multiply
8.96x = 15 * .8786
8.96x = 13.179
x = 13.179/8.96
x = 1.4709 grams of copper weighs the same as 15 grams of benzene
:
:
See if that is true, find actual volume of each
1.4709 * 8.96 = 13.179 cu cm of copper
15 * .8786 = 13.179 cu cm of benzene
