The volume occupied by 2 mol of N2 at 200 K and 10.1325 MPa pressure is
(Given that PcVCRTC=38 and PrVrTr=2.21 ), where Pr,Vr and Tr are reduced pressure, reduced volume and reduced temperature.
272.0cm3
PcVcRTc×PrVrTr=38×2.21 or Vm=(3×2.28)RTP
Vm=136.0cm3
Required volume = Vm×no.ofmoles
∴VN2=272cm3
