One litre of a gaseous mixture of two gases mixture of two gases effuses in 311 seconds while 2 litre of oxygen takes 20 minutes. The vapour density of gaseous mixture containing `CH_(4)` and `H_(2)` is:

One litre gaseous mixture is effused in 4.5 minutes and 30 seconds while 1 litre of oxygen takes 10 minutes for effusion. The gaseous mixture contains in it ethane and hydrogen. Calculate vapour density of gaseous mixture.

A gaseous mixture of H_2 and CO_2 gases contains 66 mass % of CO_2 . The vapour density of the mixture is :
