1. if 15.0mL of 4.5 M NaOH are diluted with water to a volume of 500mL, what is the molarity of the resulting solution?

2. in a acid-base titration, 33.65mL of an 0.148 M HCL solution were required to neutralize 25.00mL of a NaOH solution. What is the molarity of the NaOH solution?

3. a 0.481 gram sample of an unknown acid (HX) required 28.95 mL of 0.2103 M NaOH for neutralization to a phenolphthalein endpoit. What is the molar mass of the acid?

4. what volume of 0.1037 M HCL is necessary to neutralize 0.3643 grams Ca(OH)2? included a balanced equation?

5.calculate the molar concentration of propionic acid (HC3H5O2) in solution if 10.00mL of a propionic acid solution is neutralized with 16.85mL of 0.143 M NaOH solution.

6. calculate the mass percent of propionic acid (HC3H5O2) in solution. (Assume the density of the solution to be 1.00g/mL.)
