Samantha Muir dissolved 0.31 grams of KHP in 25.0 ml of water. She found out that it required 15.5 ml of NaOH to reach the endpoint of titration.

a. How many moles of the acid, KHP, were orinignally present before the addition of the base?

b. Calculate the concentration of the NaOH solution

c. What is the pH of the solution at the endpoint? (Ka for KHP= 3.89 x 10^-6)
