Question

. An unknown gas diffuses at a rate of 0.5 litre that of nitrogen at the

same temperature and pressure. Calculate the molar mass of the

unknown gas.

​

Answer 1

Answer:

112g/mol

Explanation:

Runkown/RN2 = 0.5

Using Graham's law of diffusion

Runkown/RN2 =[Molar mass of N2/Molar mass of unknown gas]^1/2

Molar mass of unknown gas = 112g/mol
