Question

0.48 g of an organic compound on complete combustion produced 0.22 g of CO₂. The percentage of C in the given organic compound is:

• A. 25
• B. 50
• C. 12.5
• D. 87.5

Hint:

The percentage of carbon is calculated using the ratio of carbon weight in CO₂ to the total weight of organic carbon.

Answer 1

The Correct Option is C

The percentage of carbon is calculated as:
\( \%C = \frac{12}{44} \times \frac{\text{wt. of CO}_2}{\text{wt. of O.C}} \times 100 \)

\( \%C = \frac{12}{44} \times \frac{0.22}{0.48} \times 100 = \frac{600}{48} = 12.5\% \)
