A 3 5m container is filled with 900 kg of granite (density of 2400 3 kg m/ ). The rest of the volume is air, with density equal to 3 1.15 / kg m . Find the mass of air and the overall (average) specific volume

Complete question:

A 5-m³ container is filled with 900 kg of granite (density of 2400 kg/m3). The rest of the volume is air, with density equal to 1.15 kg/m³. Find the mass of air and the overall (average) specific volume.

The mass of the air is 5.32 kg

The specific volume is 5.52 x 10⁻³ m³/kg

Explanation:

Given;

total volume of the container, = 5 m³

mass of granite, = 900 kg

density of granite, = 2,400 kg/m³

density of air, = 1.15 kg/m³

The volume of the granite is calculated as;

The volume of air is calculated as;

The mass of the air is calculated as;

The specific volume is calculated as;
