Two identical vessels contain helium and hydrogen gases at same temperature, then

Two identical vessels contain two different ideal gases at the same temperature. If the average speed of gas molecules in the first vessel is euqal to the most probable speed of molecules in the second vessel, then the ratio of the mass of gas molecules in the first vessel to that in the second vessel is

Two tanks of equal volumes contain equal masses of hydrogen and helium at the same temperature. Then :

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

A vessel contains X number of molecule of hydrogen gas at a certain temperature and pressure. How many molecules of oxygen will be present in a vessel of same volume under the same conditions of temperature and pressure? Name the law to justify your answer.

Two vessels separately contain 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 weights of A and B is :
