The number of moles of in 13.5 g is : — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

**Step-by-step solution:** **Step 1: Calculate the molar mass of $SO_2Cl_2$** $$M = S + 2(O) + 2(Cl)$$ $$M = 32 + 2(16) + 2(35.5)$$ $$M = 32 + 32 + 71 = 135 \text{ g/mol}$$ **Step 2: Use the moles formula** $$n = \frac{\text{mass}}{\text{molar mass}}$$ $$n = \frac{13.5}{135} = 0.1 \text{ mol}$$ **Answer: The number of moles is 0.1 mol (or 1/10 mol)** This is correct because dividing the given mass by the calculated molar mass directly gives the number of moles present in the sample.
