RE-NEET 2024 Chemistry Combustion Analysis MCQ Question
On complete combustion, 0.3 g of an organic compound gave 0.2 g of CO₂ and 0.1 g of H₂O. The percentage composition of carbon and hydrogen in the compound, respectively is:
4.07% and 15.02%
18.18% and 3.70%
15.02% and 4.07%
3.70% and 18.18%
Correct Answer
Detailed Explanation
The mass of carbon is calculated from CO₂ (0.2 g CO₂ contains 0.0545 g C) and the mass of hydrogen from H₂O (0.1 g H₂O contains 0.0111 g H). The percentages are calculated as (mass of element/total mass)×100.
