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 critital temperature `(T_C) as z= (P_c V_c)/( RT_c)`
Substituing values,` z= ( 12.97 xx 0.065 )/( 0.083 xx 33.2 )`
Compressibility factor = 0.306
