    From Wikipedia, molar mass of KHP = 204.22 g/mol

    (OR: Use the molar mass of KHP you commonly use.)

    KHP + KOH = K₂P + H₂O

    Mole ratio KHP : KOH = 1 : 1

    No. of moles of KHP reacted = (1.000 g) / (204.22 g/mol) = 0.004897 mol

    No. of moles of KOH reacted = 0.004897 mol

    Molarity of KOH = (0.004897 mol) / (43.3/1000 L) = 0.113 M
