A gas diffuse 1/5 times as fast as hydrogen its molecular weight is?
Answers
Given:
Gas X diffuses times as fast as hydrogen
To find:
Molecular weight of gas X
Calculation:
As the given statement states that gas 'X' diffuses 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
∴
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 =
x/5x=
1/25 = 2/M
M = 50
