Calculate the true mass (in vacuum) of a piece of aluminum whose apparent mass is 4.5000 kgkg when weighed in air. The density of air is 1.29 kg/m3kg/m3, and the density of aluminum is 2.7×103kg/m32.7×103kg/m3.

The true weight of the aluminium is 4.5021 kg

Explanation:

Given data

= 4.5 kg

= 1.29

= 2.7×

The true mass of the aluminium is given by

Put all the values in above equation we get

4.5021 kg

Therefore the true weight of the aluminium is 4.5021 kg
