Question

Calculate the molarity of a solution containing 2.66 moles of KOH in 750 mL of solution?

Answer 1

Molarity = moles of solute/volume of solution in liters.

There are 2.66 moles of KOH, the solute, and the volume of the solution is 0.750 L.

The molarity of this solution would thus be (2.66 moles KOH)/(0.750 L) = 3.55 M KOH.
