On complete combustion, 0 . 492 g of an organic compound gave 0 . 792 g of CO 2 . The % of carbon in the organic compound is (Nearest integer)

Correct answer

0

Step-by-step solution

44 grams of CO 2 contain 12 grams of carbon. Hence, one gram of carbon dioxide contain 12 44 gram of carbon. 0 . 792 gram of carbon dioxide contain 12 44   ×   0 . 792 gram of carbon Percentage of carbon = Mass of carbon Mass of organic compound   ×   100 =   12 44   ×   0 . 792 0 . 492   × 100 =   43 . 90 % So, answer is 44 .
