Question

a gaseous mixture of H2 and CO2 gas contains 66 mass % of CO2 . the vapour density of mixture is

Answer 1

A gaseous mixture of H₂ and CO₂ contain  66 % CO₂ by mass of CO₂ 

this means if mixture 100g CO₂ =66g  and H₂ =34g

Applying Dalton's law :

m mix = mH₂ + mCO₂

(n x M ) mix =(n x M )  H₂ + ( nx M )CO₂

100 x 2x  = ( 34 x 2 ) + ( 66 x 44 )

x = 14.86
