Dilutions Worksheet

1) If I add 25 mL of water to 125 mL of a 0.15 M NaOH solution, what will the

molarity of the diluted solution be?

2) If I add water to 100 mL of a 0.15 M NaOH solution until the final volume is

150 mL, what will the molarity of the diluted solution be?

3) How much 0.05 M HCl solution can be made by diluting 250 mL of 10 M

HCl?

4) I have 345 mL of a 1.5 M NaCl solution. If I boil the water until the volume

of the solution is 250 mL, what will the molarity of the solution be?

5) How much water would I need to add to 500 mL of a 2.4 M KCl solution to

make a 1.0 M solution?
