1) How many mL of 5.00M CaSO4 solution must be
diluted with water to prepare 500.0 mL of 0.900M CaSO4?
2) 20.0 mL of a stock solution of NaOH is diluted with water to prepare 150.0mL of 1.50 M NaOH solution.
Calculate the Molarity of the stock NaOH solution?
3) 12.00 mL of 3.50 M NaOH solution is diluted with 88.0 mL of water.
What is the concentration of sodium hydroxide in the diluted solution?
4) 9.0 mL of 8.0 M HCl solution is diluted with water to prepare 0.50 M HCl solution. What is the final volume of this solution?
