The molecular weight of a compound is 60. Its empirical formula is . How many atoms are present in o — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Empirical mass} = 12 + 2(1) + 16 = 30$. <br>$n = 60 / 30 = 2$. <br>$\text{Molecular formula} = (CH_2O)_2 = C_2H_4O_2$. <br>$\text{Total atoms} = 2 + 4 + 2 = 8$. [5, 16]
