Answer
The final concentration is equal to 1.76 M NaOH
Work Step by Step
1. Write the dilution expression, and solve for the final concentration ($C_2)$:
$C_1 \times V_1 = C_2 \times V_2$
- Now, divide both sides by "$V_2$":
$\frac{C_1 \times V_1}{V_2} = C_2$
$C_2 = \frac{C_1 \times V_1}{V_2} $
2. Substitute the values and calculate the final concentration:
$C_2 = \frac{(6.00 \space M) \times (75.0 \space mL)}{255 \space mL} = 1.76 \space M$
