Problem # p044 |

The pressure in a 2 m³ tank filled with nitrogen is 20 MPa and the
temperature is 50°C.

The molar mass of N_{2} is 28 kg/kmol , the universal gas
constant has a value of 8.314 kJ/(kmol K).

Determine the mass of nitrogen in the tank assuming that the nitrogen can be treated as an ideal gas.
