1) if i add 25 ml of water to 125 ml of a 0.15 m naoh solution, what will the molarity of the diluted solution be?

Answer

Explanation:

Step1: Calculate total volume

The initial volume $V_1 = 125\ mL$ and the volume of water added is $25\ mL$. The final volume $V_2=125 + 25=150\ mL$.

Step2: Use dilution formula

The dilution formula is $M_1V_1 = M_2V_2$, where $M_1 = 0.15\ M$, $V_1 = 125\ mL$, and $V_2 = 150\ mL$. We need to find $M_2$. Rearranging the formula gives $M_2=\frac{M_1V_1}{V_2}$. Substitute the values: $M_2=\frac{0.15\ M\times125\ mL}{150\ mL}$. $M_2 = 0.125\ M$

Answer:

$0.125\ M$
