1.	Two vessel separately contains two ideal gases A and B at the same temperature, the pressure of A being twice that of B. under such conditions, the density of A is found to be 1.5 times the density of B. the ratio of molecular weight of A and B isA. `1/2`B. `2/3`C. `3/4`D. `2`
Answer» Correct Answer - C `PV=nRTimplies P =(rho)/(M)RT` `M = (rhoRT)/(P) implies M prop (rho)/(P)` `(M_1)/(M_2)=3/2 xx 1/2 implies M_(1):M_(2)=3:4`.
