Question

A vessel contains equal number of moles of helium and methane. Due to a hole in the vessel, half of the gaseous mixture effused out. What is the ratio of the number of moles of Helium and Methane remaining in the vessel?
(PLEASE GIVE PROPER EXPLANATION)

Answer 1

Answer:

Hence, in a given time, the number of the moles of helium that diffuse in a given time is one half the number of moles of methane that diffuse at the same time. The ratio of the number of mole of Helium and methane remaining in the vessel is 1:2.
