From V = cylinder volume of 50 l containing nitrogen at a temperature t1 = 27 ° C, the gas is discharged so rapidly that the heat transfer gas in the cylinder with the atmosphere during the release does not have time to occur. Immediately after the closing of the valve in the cylinder gas temperature t2 = 0 ° C, the pressure p2 = 8,6 MPa. Determine the mass of the released nitrogen.
