Question

A gaseous mixture contains equal moles of $H_2 \:O_2\:and\:He$ is subjected to series of diffusion steps.The composition of effused mixture after 4 effusion steps is x:1:y respectively. Find the value of 2y + x.​

Answer 1

Answer:

As rate of effusion is inversely proportional to square root of molar mass, so ratio of hydrogen to helium (when for oxygen it is one) is 4:1.
