A compound has empirical formula and vapour density 30. The molecular formula is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Molar mass} = 2 \times 30 = 60$. $\text{Empirical mass} (CH_2O) = 12+2+16 = 30$. $n = 60/30 = 2$. $\text{Formula} = C_2H_4O_2$. [6]
