Question

A rock weighing 32.0 g is placed in in a graduated cylinder displacing the volume from 12.3 mL to 16.8 mL. What is the density of the rock in grams/cubic centimeter?

Answer 1

`"Density, "rho="Mass"/"Volume"~=7*g*mL^-1`

Explanation:

`rho` `=` `(32.0*g)/((16.8-12.3)*mL)`

Note that `1*mL=1*cm^-3`.
