A standard KHP solution is made by dissolving 2.12 grams of KHP in 100.00 mL of water. The KHP solution is then titrated with NaOH solution. It takes 23.12 mL of NaOH to reach the endpoint. What is the concentration of the NaOH?

1. KHP + NaOH ==> NaKP + H2O

mols KHP = grams KHP/molar mass KHP
Since 1 mol KHP reacts with 1 mol NaOH, you know mols NaOH = mols KHP
Then M NaOH = mols NaOH/L NaOH. You know mols NaOH and L NaOH, calculate M NaOH
