Question

The specific volume of a gas is 1.5 m³/kg. What volume does 7.5 kg of the gas occupy? What is the density of the gas?

Answer 1

$v=1.5 \;m^3/kg \\ ρ= \frac{1}{v} \\ ρ= \frac{1}{1.5} = 0.67 \;kg/m^3 \\ m=7.5 \;kg \\ V = \frac{m}{ρ} \\ V = \frac{7.5}{0.67} = 11.19 \;m^3$

Density = 0.67 kg/m³

Volume = 11.19 m³
