Question

What is the molarity of a solution of naoh if 2 liters of the solution contains 4 miles of naoh

Answer 1

If 2L contains 4 moles
then 1L contains x moles

∴ x = (4 moles × 1L) ÷ 2 L
= 2 moles

Thus it is safe to say that the molarity of NaOH is 2 mol/L or 2 mol/dm³

Answer 2

2 because M=(moles solute)/(liters solution)
