A container holds 1.5 moles1.5\text{ moles}1.5 moles of an ideal gas at a pressure of 150 kPa. The root-mean-square (r.m.s.) speed of the gas particles is 480 m s-1. The mass of each gas particle is 4.0 × 10-26 kg.
What is the volume of the container?
(Use Avogadro's constant NA=6.02×1023 mol−1N_A = 6.02 \times 10^{23}\text{ mol}^{-1}NA=6.02×1023 mol−1.)
