how do i calculate the NaOH molarity from a titration of KHP and NaOH after preparing KHP to standardise NaOH. KHP mass was 2.0378g dissoveld in distilled water to fill up a 100ml volumetric flask and only 10ml of this solution was used to in titration

  • chemistry -

    mols KHP = grams/molar mass
    You took 10mL from 100 so you took 1/10 of those mols to titrate.
    Then mols NaOH = same as mols in the titrated KHP.
    M NaOH = mols NaoH/L NaOH.
