i understand that the answer is 2. But can you please explain how you get to the answer being 2?

What volume of a 1.5 M KOH solution is needed to provide 3.0 moles of KOH?

Answer 1

(X L)(1.5 mol/L) = 3 moles

x = 3/1.5 = 2 liters

Answer 2

Molarity is in units of mol/L. If we start with 1.5M and want to get to 3 mol, we have to have 2L

1.5M * 2L = 3 mol

Answer 3

We know that,

(Vol. in L)(molarity) = no. Of moles

Vol. in L = moles/Molarity = 3/1.5= 2 L
