Question

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 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 ( M ) ( gm mol ⁻¹ ) of the given by

Correct answer: B. 4 M 15

aligned & For maximum density = d dP ( d )=0 & 3-1.2 P =0 & P =2.5 ~atm & ~d _ =3 2.5-0.6(2.5)^2=3.75 aligned V_m= M d_ = M 3.75 = 4 M 15
