Question

Given two gas samples: one of N₂ and one of He. If the two samples are at the same temperature, which will effuse at a faster rate and by what factor?

Answer 1

Molar mass of H=4.0g

Molar mass of nitrogen=28.0g

=2.65

Helium effuses 2.65 times faster than nitrogen at the same temperature.
