Mass By Volume Percentage

In an organic compound of molar mass greater than 100g//mol containing only C, H & N the mass % of C is six times the mass % of H , while the sum of mass % of C & H is 1.5 times the mass % of N . What is ("least molecular mass")/2 of compound?

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

A gaseous mixture of H_(2) and CO_(2) gas contains 66 mass % of CO_(2) . The vapour density of the mixture is :
