Question

A piece of rubber has a mass of 495 kg and a volume of 355 liters. Will it float in water, which has a density of 1.0 g/mL?

Answer 1

Compare the density of the rubber to water. If it is less that 1 g/mL then it floats in the water.

You must compare density in the same units. So convert to g/mL


`( (495kg)/(355L) )*( (1000g)/(1kg) )*( (1L)/(1000mL) ) = 1.39 g/mL`

The rubber does not float in water.
