To find the volume of the 2.75 M solution needed to make 500.0 mL of a 1.27 M solution, use the dilution formula $M_1V_1 = M_2V_2$, where $M_1$ and $V_1$ are the molarity and volume of the initial solution, and $M_2$ and $V_2$ are the molarity and volume of the final solution. Plugging in the given values: $2.75M \times V_1 = 1.27M \times 500.0mL$, solving for $V_1$ gives approximately 231 mL.
