What volume (in liters) of a 2.5 M NaOH solution contains 3.25 mol of NaOH?

• A. 0.77 L
• B. 1.30 L
• C. 0.13 L
• D. 8.13 L

Answer: (B)

Verified step by step guidance

1. Identify the known quantities: the molarity (M) of the NaOH solution is 2.5 M, and the amount of NaOH in moles is 3.25 mol.
2. Recall the definition of molarity, which relates moles of solute to volume of solution: \(M = \frac{\text{moles of solute}}{\text{volume of solution in liters}}\).
3. Rearrange the molarity formula to solve for volume: \(\text{volume} = \frac{\text{moles of solute}}{M}\).
4. Substitute the known values into the rearranged formula: \(\text{volume} = \frac{3.25\ \text{mol}}{2.5\ \text{mol/L}}\).
5. Calculate the volume from the expression to find the volume of NaOH solution that contains 3.25 mol of NaOH.
