1 M? 3. Molarity and Mass Conversions Some problems require converting grams of solute to moles before calculating molarity. This adds an extra layer of complexity. Example: What is the molarity of a solution made by dissolving
les / M. So, volume = 3 moles / 1.5 M = 2 liters. If a solution has a molarity of 0.75 M and contains 1.5 liters, how many moles of solute are present? Moles of solute = Molarity × Volume = 0.75 M × 1.5 L = 1.125 moles. How can you prepare 500 mL of a 2 M NaCl solutio
g Volume of solution = 500 mL = 0.500 L Calculate moles of NaCl: Molar mass of NaCl = 22.99 (Na) + 35.45 (Cl) = 58.44 g/mol Moles of NaCl = \(\frac{\text{mass}}{\text{molar mass}}\) Moles = \(\frac{10.0\, g}{58.44\, g/mol}\) ≈ 0.1712 mol Calculate mo
