The number of moles of Mohr's salt that contain 4.8 g of oxygen atoms is : — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Total Oxygen atoms in Mohr's salt formula: $4 (SO_4) + 4 (SO_4) + 6 (H_2O) = 14$ Oxygen atoms. <br>Moles of O atoms $= 4.8 / 16 = 0.3$ mol. <br>$\text{Moles of compound} = \text{moles of O} / 14 = 0.3 / 14 \approx 0.021$ mol. Closest option is 0.02.
