To find the volume of 0.10 M NaOH that can be prepared from 250 mL of 0.30 M NaOH, we 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: $0.30 \, \text{M} \times 0.250 \, \text{L} = 0.10 \, \text{M} \times V_2$, solving for $V_2$ gives $V_2 = 0.75 \, \text{L}$.
