Question
**Question:** How many grams (g) of solute are present in 75 mL of a 0.50 M glucose (C₆H₁₂O₆) solution of glucose? **Given Data:** - Molar mass of glucose = 180.15 g/mol **Options:** - A. 68 g - B. 7.0 g - C. 0.038 g - D. 37.5 g - E. 6.8 g **Explanation:** To find the grams of glucose in the solution, use the following steps: 1. Convert the volume from mL to L: - 75 mL = 0.075 L 2. Use the formula for moles of solute: - Moles of solute = Molarity (M) × Volume (L) - Moles of glucose = 0.50 M × 0.075 L = 0.0375 moles 3. Convert moles to grams: - Grams = Moles × Molar mass - Grams of glucose = 0.0375 moles × 180.15 g/mol = 6.8 g **Correct Answer:** - E. 6.8 g
