A 2-m3 rigid vessel contains helium initially at a gage pressure and temperature of 320 kPa and 315 K respectively. Because of the leaks in the fittings of the vessel, the gage pressure dropped to 280 kPa and the temperature decreased to 300 K, determine the mass of the helium that leaked out and also the mass of nitrogen that remained in the vessel.
