Answer to Question #307914 in Chemistry for grey tyrant

Question

How many milliliters of a 0.625 M KOH solution would contain 0.0250 mole of KOH?

Answer 1

Solution:

Molarity = Moles of solute / Liters of solution

Therefore,

Liters of KOH solution = Moles of KOH / Molarity of KOH

Liters of KOH = (0.0250 mol) / (0.625 M) = 0.04 L = 40 mL

Volume of KOH solution = 40 mL

Answer: 40 milliliters of KOH solution
