`10 dm^(3)` of `N_(2)` gas and `10 dm^(3)` of gas `X` contain the same number of molecules at the same temperature, the gas `(X)` may be

10dm^(3) of N_(2) gas and 10 dm^(3) of gas X at the same temperature contain the same number of molecules The gas X is

10 dm^(3) of N_(2) gas and 10 dm^(3) of gas X at the same temperature and pressure contain the same number of molecules. The gas X is

10 dm^3 of N_2 gas and 10 dm^3 of gas x at the same temperature contain the same number of molecules. The gas x is CO , CO_2 , H_2 , NO

2.24 dm^3 of methane at N.T.P. contain same number of molecules as are present in ________ .

A 0.5 dm^(3) flask contains gas A and 1 dm^(3) flask contains gas B at the same temperature. If density of A= 3g//dm^(3) and that of B= 1.5g //dm^(3) and the molar mass of A= 1//2 of B , the ratio of pressure excerted by gases is:

A 0dm^(3) flask contains gas A and 1 dm^(3) flask contains gas B at the same temperature. If density of A = 3.0 g dm^(-3) and that of B = 1.5 g dm^(-3) and the molar mass of A = (1)/(2) of B, then the ratio of presuure exerted by gases is
