The density of air is 28.86. Calculate the relative molecular mass for each pair. If it is higher than 28.86 then it would be collected by downward delivery and upward displacement of air, if it is lower than 28.86 it would be collected by upward delivery and downward displacement of air. Even if it is 28 being nitrogen it would be collected by upward delivery and downward displacemnt
