Question

An Unknown Gas Diffuses At A Rate Of 2.5 Time That Of Nitrogen At The Same Temperature And Pressure Calculate Molar Mass Of The Unknown Gas​

Answer 1

Answer:

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:

Squaring both sides and solving for  

Hence, the molar mas of unknown gas is 112 g/mol.
