1.	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.
Answer» SOLUTION :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`.
