Given:

Gas X diffuses \frac{1}{5} times as fast as hydrogen

To find:

Molecular weight of gas X

Calculation:

As the given statement states that gas 'X' diffuses \frac{1}{5} times as fast as hydrogen, Rate of gas 'x' = 1

Rate of hydrogen gas = 5

Molecular weight of hydrogen = 2.02

Molecular weight of gas x = ?

According to Graham's law

\frac{1}{5} = \sqrt{\frac{2.02}{x}

When the above equation is solved it gives 50 which is the molecular weight of gas 'x'

Conclusion:

The molecular weight of gas X is 50g.

Answer:

50

Explanation:

Rate of diffusion of hydrogen be x, then rate of diffsion of unknown gas will be-

1/5 x 5x = x

By the Graham's law of Diffusion,

r1/r2 = \sqrt{M2/M1}

x/5x= \sqrt{2/M}

1/25 = 2/M

M = 50
