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 is

Two vessels of the same volume contain the same gas at same temperature. If the pressure in the vessels is in the ratio of 1 : 2, then

Two separate bulbs contains ideal gases P and q, respectively maintained at the same temperature. The density of gas P is twice of that of the Q, and the molecular weight of the gas P is half of that of the gas Q. The ratio of the pressure of gas P to that of gas Q is

The density of gas A is twice that of B at the same temperature the molecular weight of gas B is twice that of A. The ratio of pressure of gas A and B will be :

If the density of a gas A is 1.5 times that of B, then the molecular mass of A is M. The molecular mass of B will be
