Question

On complete combustion, 0.246 g of an organic compound gave 0.198g of carbon dioxide and 0.1014 g of water. Determine the percentage composition of carbon and hydrogen in the compound.

Solution

We have given,
Mass of Organic compound= 0.246 g
Mass of Carbon dioxide = 0.198 g
Mass of Water = 0.1014 g
Percentage of carbon:
Mass of carbon dioxide = 0.198 g
$therefore$ Percentage of carbon
$equals space 12 over 44 cross times fraction numerator Mass space of space CO subscript 2 over denominator Mass space of space compound end fraction cross times 100 equals 12 over 44 cross times fraction numerator 0.198 over denominator 0.246 end fraction cross times 100 space equals space 21.95 space percent sign$

Percentage of hydrogen:
Mass of water = 0.1014 g
$therefore space space space space Percentage space of space hydrogen space space space space space space space space space space space space space equals space 2 over 18 cross times fraction numerator Mass space of space straight H subscript 2 straight O over denominator Mass space of space compound end fraction cross times 100 space space space space space space space space space space space space space equals space 2 over 18 cross times fraction numerator 0.1014 over denominator 0.246 end fraction cross times 100 space equals space 4.58 percent sign$
