120 g of an organic compound which contains only carbon and hydrogen on complete combustion gives 330 g of CO 2 and 270 g of water. The percentage of carbon and hydrogen in the organic compound are respectively

Options

  1. A25 and 75
  2. B40 and 60
  3. C60 and 40
  4. D75 and 25

Correct answer

D. 75 and 25

Step-by-step solution

Weight of the organic compound, W=120g, Weight of carbondioxide ( x ) =330g Weight of water ( y ) =270g Percentage   of   carbon = 12 44 X x W X 100                                                                               = 12 44 X 330 120 X 100                   &
