Question
0.765 g of an acid gives 0.535 g of $\mathrm{CO}_2$ and 0.14 g of $\mathrm{H}_2 \mathrm{O}$. Then the ratio of the percentage of carbon and hydrogen is(a) $1: 9$(b) $20: 16$(c) $18: 11$(d) $19: 2$
Step 1
The molar mass of $\mathrm{CO}_2$ is approximately 44.01 g/mol. \[ \text{Moles of } \mathrm{CO}_2 = \frac{0.535 \text{ g}}{44.01 \text{ g/mol}} \approx 0.01214 \text{ mol} \] Show more…

$0.765 \mathrm{~g}$ of an acid gives $0.535 \mathrm{~g}$ of $\mathrm{CO}_{2}$ and $0.14 \mathrm{~g}$ of $\mathrm{H}_{2} \mathrm{O}$. Then the ratio of the percentage of carbon and hydrogen is (a) $1: 9$ (b) $20: 16$ (c) $18: 11$ (d) $19: 2$
On combustion, $0.2 \mathrm{~g}$ of an organic compound containing carbon, hydrogen and oxygen yields $0.147$ g carbon dioxide and $0.12 \mathrm{~g}$ water. The percentage of carbon, hydrogen and oxygen respectively in the compound is (a) $22.5,8.7$ and $68.8$ (b) $20,6.7$ and $73.3$ (c) $18.2,9.5$ and $72.3$ (d) $28.9,12.8$ and $58.8$
