Question

Hydrogen diffuses 6 times as fast as an unknown gas. What is the relative molecular mass of the gas?

Answer 1

Answer:

plz mark me brainlist....

Explanation:

According to Graham's law of diffusion,

rate of diffusion ∝Molarmass1

Hydrogen diffuses six times faster than X.

So, 16=2MolarmassX⟹36×2=MolarmassX

Molar mass of X=72

Answer 2

Answer:

Explanation:

Molar mass of x=72......
