Question

The density of aluminum is 2.7 g cm3 what is its density in kilograms per cubic meter

Answer 1

The only thing that we have to do in this problem is to convert the units.

We know that:

1000 g = 1 kg

100 cm = 1 m

Therefore:

density = (2.7 g / cm^3) * (1 kg / 1000 g) * (100 cm / m)^3

density = 2700 kg / m^3
