The molecules of a gas A travel four times faster than the molecules of gas B at the same temperature. The ratio of molecular weight (M_A // M_B) will be

The mean speed of Helium atoms is 4 times that of the molecules of a gas x at the same temperature. The molecular weight of x is

When 4 g of an ideal gas A is introduced into an evacuated flask kept at 25^(@)C , the pressure is found to be one atmosphere. If 6 g of another ideal gas B is then added to the same flask, the pressure becomes 2 atm at same temperature. The ratio of molecular weights (M_(A) : M_(B)) of the two gases would be

The destiny of a gas A is four times that of gas B. if the molar mass of A is M that of B is
