Question

Qus.1 - 1 mole of sulphur dioxide occupies a volume of 350 ml at 27°C
and 5x10 Pa pressure. Calculate the compressibility factor of
the gas. Is it less or more compressible than an ideal gas?

Qus.2- 34.05 ml of phosphorous vapour weights 0.0625g at 546°C
and 0.1 bar pressure. What is the molar mass of phosphorous?​

Please solve these questions...☺️

ANS.1

70.16

first convert volume into litres and temperature into Kelvin. We know the that compressibility factor is equal to

$\frac{pv}{rt}$

we can put the numerical values of the following and get the compressibility factor of the gas.

Since the CF of an ideal gas is 1, gases with CF more than one will be less compressible than an ideal gas. Since the CF of the given gas is more than 1, therefore the It is less conpressible than an ideal gas.
