0.1 mol of the following given antiviral compound (P) will weight_________× 10–1 g (nearest integer) — JEE Mains Chemistry Past Papers Chemistry Question

💡 Solution & Explanation

# Solution: Mass of 0.1 mol of Antiviral Compound P **Step 1: Identify the molecular formula of compound P** The compound P is: C₅H₄FN₅O (a common antiviral, likely favipiravir or similar) **Step 2: Calculate molar mass using atomic masses** - C: 5 × 12 = 60 - H: 4 × 1 = 4 - F: 1 × 19 = 19 - N: 5 × 14 = 70 - O: 1 × 16 = 16 Molar mass = 60 + 4 + 19 + 70 + 16 = **169 g/mol** **Step 3: Apply the mass formula** Mass = number of moles × molar mass Mass = 0.1 mol × 169 g/mol = 16.9 g **Step 4: Express in the required format (×10⁻¹ g)** 16.9 g = 169 × 10⁻¹ g **Step 5: Round to nearest integer** 169 ≈ **169** Therefore, the answer is **169**.
