A NaOH solution contains 1.90 mol of NaOH and has a concentration of 0.555 M. What is the volume of the solution in liters?

• A. 1.05 L
• B. 3.42 L
• C. 0.555 L
• D. 0.292 L

Answer: (B)

Verified step by step guidance

1. Identify the known quantities: the amount of solute (NaOH) is 1.90 mol, and the concentration (molarity, M) is 0.555 M.
2. Recall the definition of molarity: \(M = \frac{\text{moles of solute}}{\text{volume of solution in liters}}\).
3. Rearrange the molarity formula to solve for volume: \(\text{Volume} = \frac{\text{moles of solute}}{M}\).
4. Substitute the known values into the equation: \(\text{Volume} = \frac{1.90\ \text{mol}}{0.555\ \text{mol/L}}\).
5. Calculate the volume using the above expression to find the volume of the NaOH solution in liters.
