The weight of one molecule of a compound is: [1] — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Molar mass $= (60 \times 12) + (122 \times 1) = 720 + 122 = 842$ g/mol. <br>Weight of 1 molecule $= \text{Molar mass} / N_A = 842 / (6.022 \times 10^{23}) \approx 1.398 \times 10^{-21}$ g $\approx 1.4 \times 10^{-21}$ g. [1]
