1.) Calculate the volume of concentrated NaOH solution (which contains 500.00g NaOH per liter of solution) that you will need to make 1.00L of a 0.100 M NaOH solution 

2.) Calculate the volume of 0.105M NaOH(aq) necessary time react with 23.50mL of 0.10M HCl(aq)

3.) A titration of 20.50mL HCl(aq) of an unknown molarity requires 18.45mL of 0.085M NaOH solution. What is the molarity of the HCl solution?

4.) A student adds 25.00mL of distilled water to a 15.00mL sample of HCl of an unknown molarity and titrates this against a 0.095 M NaOH solution. Will the addition of water interfere with the determination of the molarity of the HCl sample? Why or why not?
