What volume of a 2.00 molar standard solution of NaOH is needed to prepare 1.00 L of a 0.0250 molar solution?

To prepare a diluted solution from a concentrated one, you can use the dilution formula: $C_1V_1 = C_2V_2$, where $C_1$ and $V_1$ are the concentration and volume of the initial solution, and $C_2$ and $V_2$ are the concentration and volume of the final solution. Plugging in the given values: $2.00 \, \text{M} \times V_1 = 0.0250 \, \text{M} \times 1.00 \, \text{L}$. Solving for $V_1$ gives $V_1 = \frac{0.0250 \, \text{L}}{2.00} = 0.0125 \, \text{L}$, or 12.5 mL.
