120 of an organic compound that contains only carbon and hydrogen gives 330g of CO 2 and 270g of water on complete combustion. The percentage of carbon and hydrogen, respectively are.
Text Solution
Verified by ExpertsThe correct answer is:
D
Given mass of organic compound =120
mass of CO 2 (g) = 330g
mass of H 2 O( 
) = 270g
mass of carbon = 
x12
% of carbon = 
x 100 = 75%
mass of hydrogen = 
x 2
= 
x2 = 30g
% of hydrogen = 
x 100 = 25%
