an NaOH solution contains 1.90 mol of NaOH, and its concentration is 0.555 M. What is the volume of the solution?

The volume of solution that contains 1.9 moles of NaOH is 3.42 L

Explanation:

To solve the question, we note that the solution contains 1.9 moles of 0.555 M NaOH

Therefore, 1000 mL contains 0.555 moles of NaOH

1000/0.555 mL contains 1 mole of NaOH

1.9 * 1000/0.555 mL contains 1.9 moles of NaOH

Therefore, the volume of solution that contains 1.9 moles of NaOH is 1.9 * 1000/0.555 mL or 3423.42342 mL = 3.42 L.
