0.48 g of an organic compound on complete combustion produced 0.22 g of CO ₂ . The percentage of C in the given organic compound is

Options

  1. A25
  2. B50
  3. C12.5
  4. D87.5

Correct answer

C. 12.5

Step-by-step solution

Given, Mass of organic compound =0.48 ~g Mass of CO ₂ produced =0.22 ~g % C =? Using formula % C = 12 44 mass of CO ₂ mass of organic compound 100= 12 44 0.22 0.48 100=12.5 %
