For a non-ideal gas, the compressibility factor (Z) is defined as
`Z=(PV_(m))/(RT),V_(m)`= molar volume
Compressibility of an unknown gas at 600 K and `1.0` atm was found to be `1.2` Also, this gas was found to effuse `1.58` times slower than the pure methane gas under identical conditions Take `R=0.0821` L-atm-`mol^(-1)k^(-1)`
Density of the gas in the above mentioned experimental condition is:
A. `0.98 gL^(-1)`
B. `0.68 gL^(-1)`
C. `1.02 gL^(-1)`
D. `1.47 gL^(-1)`
