What is the grams of solute needed to prepare the following solutions in1.2L of a 3.0M NaOH solution

Oct 20th, 2014

Molarity of solution = 3.0 M

Volume of Solution = 1.2 L

Moles of NaOH required = Molarity * Volume = 3.0 * 1.2 = 3.6 moles

Mass of NaOH required = Moles of Na OH * Molar mass of NaOH

Mass of NaOH required = 3.6 * 40 = 144 grams (Answer)
