The density of vapour of a substance (X) at 1 atm pressure and 500 K i – InterviewSolution

1.	The density of vapour of a substance (X) at 1 atm pressure and 500 K is 0.8 kgm3. The vapour effuses through a small hole at a rate of 45 times slower than oxygen under the same condition. What is the compressibility factor (Z) of the vapour?
Answer» The density of vapour of a substance (X) at 1 atm pressure and 500 K is 0.8 $\frac{k g}{m^{3}}$ . The vapour effuses through a small hole at a rate of $\frac{4}{5}$ times slower than oxygen under the same condition. What is the compressibility factor (Z) of the vapour?
