To standardize a solution of NaOH, one uses a primary standard called potassium hydrogen phthalate (KHP). It is a monoprotic acid. It has a molar mass of 204.33g/mol. Suppose you weigh out .556g of KHP and dissolve it in water. It requires 14.48 mL of NaOH to reach the endpoint. What is the concentration of the NaOH solution?

mols KHP = grams/molar mass = ?
mols NaOH = mols KHP
M NaOH = mols NaOH/L NaOH
mols NaOH = mols KHP
M NaOH = mols NaOH/L NaOH
