Question

A mixture of gases h2 and O2 gases are in the ratio 1:4 what is the molar ratio of the two gases in the mixture ?

Answer 1

Number of moles (n) = Given mass (m) / Molar mass (M)

As the ratio by weight of Hydrogen and Oxygen is 1:4
Molar ratio will be =  =  =  = 

The molar ratio of Hydrogen and Oxygen is 4:1

Answer 2

Solution

Mass of H2= 1+1=2

mass of o2= 16+16= 32

Mixtures found= 2H2o=2*2+ 16

= 20

Molar rati of hydrogen= 2/20= 1:10

molar ratio of oxyegen= 32/36= 16/20= 4:5
