    The molar concentration of H3PO4 solution is calculated as below

    find the moles of NaOH reacted = molarity x volume

    = 35.5 x0.150 = 5.325 moles

    write a balanced reacting equation

    =NaOH + 3 H3PO4 = Na3PO4 + 3H2O

    by use of reacting ratio between NaOH to H3PO4 which is 1:3 the moles of H3Po4 is therefore

    = 5.325moles/3 = 1.775 moles

    molar concentration is therefore of H3PO4 = moles / volume

    =1.775/55.3 = 0.0320 M of H3PO4
