A rock has a specific gravity of 232 and a volume of 142 tim

A rock has a specific gravity of 2.32 and a volume of 1.42 times 10^-4 m^3. How much does it weigh?

Specific gravity = density of rock/density of water.

Density of water = 1000 Kg/m^3

So, density of rock = 2.32*1000 = 2320 Kg/m^3.

Mass of the rock = Density of the rock*volume of the rock = 2320 * 1.42*10^-4 = 0.32944 kg.

So weight of the rock = 0.32944*9.81 = 3.232 N.
