Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.2000 g of KHP (KC8H5O4, 204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the titration requires 9.53 mL of NaOH(aq).

a. What is the concentration of your NaOH(aq) solution?
b. Determine the number of moles of NaOH(aq) that would be required to titrate 250.00 mL of your Kool-Aid solution.
