In an industrial process nitrogen is heated to 500k at constant volume of 1m3. the gas enters the container at 300k and 100atm. the mass of the gas is 92.4kg.

In an industrial process nitrogen is heated to 500K at constant volume of 1m3. The gas enters the container at 300K and 100atm. The mass of the gas is 92.4kg. Use vanderwaals equation to determine the approximate pressure of the gas at its working temperatue of 500K. For nitrogen a=1.352dm6atmmol-2, b=3.19X10^-2dm3 mol-1.
