# Learning Laws of Thomas Graham by solving this (1) =)

**Chemistry**Level pending

Let set that they have the same condition. The rate of diffusion of hydrogen gas is 4 times bigger than the rate of diffusion of gas X , so What is the MOLAR MASS of gas X?

You can solve this question by using:

(velocity of Hydrogen)^2 / (velocity of Oxygen)^2 = (Molar mass of oxygen / Molar mass of Hydrogen)

What is this law talking about ?

-The rate of effusion of a gas is inversely proportional to the square root of either the density or the molar mass of the gas.
