Choose the correct option from the following.

For 1 mol of gas, the plot of pV vs. p is shown below. p is the pressure and V is the volume of the gas

What is the value of compressibility factor at point A ?

Which amongst the given plots is the correct plot for pressure (p) vs density (d) for an ideal gas?

An evacuated glass vessel weighs 40.0 g when empty, 135.0 g when filled with a liquid of density 0.95 g mL^$-$-1 and 40.5 g when filled with an ideal gas at 0.82 atm at 250 K. The molar mass of the gas in g mol^$-$-1 is :

(Given : R = 0.082 L atm K^$-$-1 mol^$-$-1)
