0.5 g of an organic compound on combustion gave 1.46 g of \(\mathrm{CO}_2\) and 0.9 g of \(\mathrm{H}_2 \mathrm{O}\). The percentage of carbon in the compound is _______. (Nearest integer) [Given : Molar mass (in \(\mathrm{g} \mathrm{mol}^{-1}\)) \(\mathrm{C}: 12, \mathrm{H}: 1\), O: 16]
- A 20
- B 40
- C 60
- D 80
Answer & Solution
Correct Answer
(D) 80
Step-by-step Solution
Detailed explanation
Organic Compound\(\rightarrow \mathrm{CO}_2\) Applying POAC on ' C ' (mole) of ' C ' in compound \(=\mathrm{n}_{\mathrm{CO}_2} \times 1\) So mass of ' C ' in compound \(=\frac{1.46}{44} \times 12\) So, \(\%\) of ' C ' in compound…
