To prepare 25 mL of 0.25 M MgCl₂ solution from a 0.75 M MgCl₂ stock solution, you should mix ________.

Question

Quizplus · Accepted Answer

To prepare a diluted solution, use the dilution formula $C_1V_1 = C_2V_2$, where $C_1$ and $V_1$ are the concentration and volume of the stock solution, and $C_2$ and $V_2$ are the concentration and volume of the final solution. Plugging in the given values: $0.75 \, \text{M} \times V_1 = 0.25 \, \text{M} \times 25 \, \text{mL}$, solving for $V_1$ gives $V_1 = \frac{0.25 \times 25}{0.75} = 8.33 \, \text{mL}$.
