A mixture of `O_(2)` and gas `"Y"` `( mol. wt. 80)` in the mole ratio `a:b` has a mean molecular weight 40. What would be mean molecular weight, if the gases are mixed in the ratio `b:a` under identical conditions ? ( gases are )

The ratio of rates of diffusion of gases A and B is 1 : 0.707. IF the molecular weight of B is 32, the molecular weight of A is

At 400 K, the root mean square (rms) speed of a gas X (molecular weight = 40) is cgual to the most probable speed of gas Y at 60K. The molecular weight of the gas Y is

The molecular weights of two gases are M_(1) and M_(2) ,then at a temperature the ratio of root mean square velocity v_(1) and v_(2) will be

Gases best follow the facts given below A) An ideal gas obeys the mathematical relation PV=nRT B) Rates of diffusion of two gases are in the reciprocal ratio of square roots of their molecular weight C) Total pressure of a mixture of non reacting gases is given by the algebric sum of their partial pressure An ideal gas is captured in a glass tube of uniform arca of cross section by a water column at a given temperature as shown If the tube is held vertical, by what length the water column descends down? (Density of mercury=13.6gm/cc) (P_(atm)=76cm of Hg)

Two moles of an ideal gas X occupying a volume V exerts a pressure P. The same pressure is exerted by one mole of another gas Y occupying a volume 2V. If the molecular weight of Y is 16 times the molecular weight of X, find the ratio of the rms speeds of the molecules of X and Y.
