Question

4gm of Hydrogen effused through a pinhole in 10 s at same constat temperature and pressure.The amount of oxygen effused in the same time interval and the same conditions of temperature and pressure would be -
(a) 4 gm
(b) 8 gm
(c) 16 gm
(d) 32 gm​

Answer 1

Answer:

(c) 16gm

Explanation:

The rate of diffusion is inversely proportional to the square root of molar mass.

Wo₂ W H₂ MH₂ Wo₂

The molecular weights of hydrogen and oxygen are 2 g/mol and 32 g/mol respectively. Substitute values in the above expression.

4 WH₂ 2 32 = - 4

WH₂ = 4 x 4 = 16 g

Hence, 16 g of hydrogen would have diffused under identical conditions.

Answer 2

Answer:

The rate of diffusion is inversely proportional to the square root of molar mass.

Wo₂ W H₂ MH₂ Wo₂

The molecular weights of hydrogen and oxygen are 2 g/mol and 32 g/mol respectively. Substitute values in the above expression.

4 WH₂ 2 32 = - 4

WH₂ = 4 x 4 = 16 g

Hence, 16 g of hydrogen would have diffused under identical conditions.
