Under identical conditions of pressure and temperature,

2 \mathrm{L}

of gaseous mixture

\left(\mathrm{H}_{2}\right.

and

\left.\mathrm{CH}_{4}\right)

effuses through a hole in 5 minutes whereas

2 \mathrm{L}

of gas

X

of molecular mass 36 takes 10 minutes to effuse through the same hole. The mole ratio of

\mathrm{H}_{2}: \mathrm{CH}_{4}

in the mixture is

View answer and explanation

Correct option: D

1: 1

Option D (

1: 1

) is correct because Graham's law of effusion relates the rate of effusion to the square root of the molar mass. By comparing the effusion rates of the mixture and gas X, and using the given molecular mass of X, the mole ratio of H2 and CH4 can be determined to be 1:1.
