JEE Main 2025 Chemistry question
0.5 g of an organic compound on combustion gave 1.46 g of and 0.9 g of . The percentage of carbon in the compound is . (Nearest integer) [Given : Molar mass (in g mol⁻¹) C : 12, H : 1, O : 16]
Answer: 80
Solution
Mass of C = (1.46/44)×12 = 0.398g; % C = (0.398/0.5)×100 = 79.63% ≈ 80.
