Prоblem 3 (35 pts) A rigid, аdiаbаtic tank with vоlume 2 m3 is initially filled with pure hydrоgen at a temperature of 300 K and a pressure of 500 kPa. The tank is connected through a valve to a source of pure helium that is at a temperature of 500 K and a pressure of 3000 kPa. The valve is opened and 2 kg of helium is allowed to enter the tank. Model the hydrogen and helium as ideal gases with constant specific heat capacities. The molar heat capacities, molar masses and universal gas constant are listed below. a.) Determine the mass of hydrogen initially in the tank (kg).
