At same temperature and pressure of an ideal gas

N_(2)O and CO_(2) have the same rate of diffusion under same conditions of temperature and pressure. Why ?

A. Rate of diffusion of H_2 is 1.44 times of He. R: Under similar conditions of temperature and pressure all gases diffuse with same velocity.

Both N_(2)O and CO_(2) have similar rates of diffusion under same conditions of temperature and pressure. Explain

4.4 g of an unknown gas occupies 2.24 L of volume at standard temperature and pressure, The gas may be

1.40L of an unknown gas requires 57 second to diffuse and the same volume of N_(2) gas takes 84 second to diffuse at the same temperature and pressure. What is the molecular mass of the unknown gas?

A certain volume of argon gas (Mol. Wt.=40) requires 45s to effuse through a hole at a certain pressure and temperature. The same volume of another gas of unknown molecular weight requires 60s to pass through the same hole under the same conditions of temperature and pressure. The molecular weight of the gas is:
