Question 31

Which pair of species has same percentage of carbon

Solution

Compounds with the same empirical formula have the same percentage composition. $$\text{CH}_3\text{COOH}$$ ($$\text{C}_2\text{H}_4\text{O}_2$$) and $$\text{C}_6\text{H}_{12}\text{O}_6$$ both have empirical formula $$\text{CH}_2\text{O}$$, giving $$40\%$$ carbon. Ethanol has about $$52\%$$ and sucrose about $$42\%$$ carbon, so only pair a matches.
