We can use the ideal gas law equation to find the volume of the gas. PV = nRT P - pressure - 400 kPa V - volume n - number of moles - 4.00 mol R - universal gas constant - 8.314 Jmol⁻¹K⁻¹ T - temperature - 300.0 K substituting these values in the equation 400 000 Pa x V = 4.00 mol x 8.314 Jmol⁻¹K⁻¹ x 300.0 K V = 24.9 dm³ Volume is 24.9 dm³
