The values of critical pressure, critical volume and critical temperature for hydrogen gas are 12.97bar, `0.005 Lmol^(-1)` and 33.2K. Calculate the compressibility factor.

Explanation

Compressibility factor (z) for one mole of gas is given interms of critical pressure `(P_C)`, critical volume `(V_C)` and critical temperature `(T_C)` as `z= (P_C V_C)/(RT_C)`
Substituting values , `z = (12.97 xx 0.065)/(0.032 xx 33.2) = 0.306`.
