How much KHP is in samples 2 and 3?
%KHP = (mL x M x mmolar mass/mass sample)
You know mL NaOH, M NaOH, millimolar mass KHP is 0.20422; solve for %KHP. Then substitute %KHP and new mass of samples 2 and 3 and solve for mL NaOH.
If KHP sample 1 requires 22.47 mL of aqueous NaOH, how many milliliters of NaOH should be needed for samples 2 and 3?
