Paragraph: 1 mole of a real gas is taken in a container at T kelvin, its density, $d$ varies with pressure as $d=3 P-0.6 P^2$. Where $d$ is expressed in gm/L and $\mathbf{P}$ is expressed in atm. Answer the following questions.Question: When 1 mole of the above gas attains maximum density at the same temperature, then volume of the container (in litre) in terms of molar mass $(\mathrm{M}) \left(\mathrm{gm} \mathrm{mol}^{-1}\right) of the given by$
