Question

what is the final concentration of 500. ml of a solution made from 125. ml of 3.0 m naoh? ? m naoh

Explanation:

Step1: Recall dilution formula

The dilution formula is \( M_1V_1 = M_2V_2 \), where \( M_1 \) is initial molarity, \( V_1 \) initial volume, \( M_2 \) final molarity, \( V_2 \) final volume.

Step2: Identify known values

\( M_1 = 3.0 \, M \), \( V_1 = 125 \, mL \), \( V_2 = 500. \, mL \), find \( M_2 \).

Step3: Rearrange formula for \( M_2 \)

\( M_2=\frac{M_1V_1}{V_2} \)

Step4: Substitute values

\( M_2=\frac{3.0 \, M\times125 \, mL}{500. \, mL} \)

Step5: Calculate

\( \frac{375}{500}=0.75 \, M \)

Answer:

\( 0.75 \, M \)
