Solution

The correct option is B CO = 32.18 and CO2 = 67.82

Molecular mass of the mixture M = dRTP==1.5×0.0821×303×760730=38.85gm/mol
Let the total number of moles be 'x'.
Let 'x' = no. of moles of CO.Then no. of moles of CO2 = (1 - x)
Molecular Mass of mixture = x × 28 + (1 - x)44 = 38.85
x = 0.3218
% of CO = 32.18 and % CO2 = 67.82
