Ideal Gas Law

The pressure in a 2 m³ tank filled with nitrogen is 20 MPa and the temperature is 50°C.
The molar mass of N2 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.
