0.5 g of an organic compound on combustion gave 1.46 g of $ CO_2 $ and 0.9 g of $ H_2O $. The percentage of carbon in the compound is ______ (Nearest integer) $\text{(Given : Molar mass (in g mol}^{-1}\text{ C : 12, H : 1, O : 16})$
0.5 g of an organic compound on combustion gave 1.46 g of $ CO_2 $ and 0.9 g of $ H_2O $. The percentage of carbon in the compound is ______ (Nearest integer) $\text{(Given : Molar mass (in g mol}^{-1}\text{ C : 12, H : 1, O : 16})$
Show Hint
Correct Answer: 80
Solution and Explanation
Organic Compound → CO2
Applying POAC on ‘C’
Option (mole) of ‘C’ in compound = $n_{\text{CO}_2} \times 1$
So mass of ‘C’ in compound = $\dfrac{1.46}{44} \times 12$
So, % of ‘C’ in compound =
\[
\dfrac{1.46}{44} \times \dfrac{12}{0.5} \times 100
\]
= 79.63
