    3NaOH + H3PO4 ---> Na3PO4 + 3H2O As we can see 3 moles of NaOH reacts with 1 mole of H3PO4 . 1st find the no. of moles of NaOH use n =cv n= no. of moles C = concentration V = Volume n= 1* 0.75 = 0.75 moles 3 moles of NaOH will react with 1 mole of H3PO4 so how much of H3PO4 will react with 0.75 moles of NaOH. that would be 075/3 = 0.25 moles of H3PO4
