To make a solution of 0.500 mol L^-1, we need to dissolve 0.500 moles of the solute in a solvent. The volume of the solvent required will depend on the concentration of the solute in the solution. Since the concentration (0.500 mol/L) is given, we can use it to calculate the volume of the solvent required. We know that: - Concentration (C) = Number of moles of solute (n) / Volume of solution (V) - Rearranging this formula: V = n / C Substituting the values: - n (number of moles of solute) = 0.500 mol - C (concentration) = 0.500 mol/L V (volume of solution) = n / C = 0.500 mol / 0.500 mol/L = 1.00 L Therefore, the best choice is (C) enough solvent to make 1.00 L of solution.
