tc and pc of gas are 400k and 41 atm respectively then vc is

Critical temperature is the temperature above which a gas cannot be liquified. It is denoted as Tc.
pc is the Critical pressure, Vc is the critical molar volume
R= 0.082 L atm K-1 mol-1

Vc = 3b  (from Ideal gas law)
‚Äčand b = RTc8pc=0.082 L atm K1 mol1×400K8×41atm=0.1 Lmol-1
Vc = 3b = 0.3 Lmol-1
