Calculate the concentration, in molarity, of a solution prepared by adding 9 mL of water to 1 mL of 0.1 M HCl solution.
If 2.0 mL of 0.010 M NaOH is mixed with enough water to make the total volume 8 mL, what is the molarity of the resulting solution?

ASSUMING that the 9 mL + the 1 mL adds to 10 mL of solution (which may not be correct), then you have 0.1M x 1/10 = ?
