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?

b.false that your answer

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
