4. How much water would be needed to dilute at 750 ml solution of 2.8M HCl to a 1.0 M solution? 5. If 550 mL of a 3.50 M KCl solution is left out to evaporate until the volume is 275 mL, what would the
new Molarity be?

6. Extra Credit: A solution of H, SO, has a molarity of 0.14 mol/L in 750 mL. If 250 mL of water is added:
a. What is the new molarity of the solution?
