Question

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

Answer 1

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

Step-by-step 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.
