Hello guys plz answer this question...!

Answer 1

Answer:- 
Solution:- The balanced equation between potassium hydroxide and phosphoric acid is:
3KOH+H_3PO_4\rightarrow \rightarrow K_3PO_4+3H_2O3KOH+H3​PO4​→→K3​PO4​+3H2​O
from this equation, there is 1:3 mol ratio between phosphoric acid and water.
So, if 1 mole of phosphoric acid is completely neutralized then we get 3 moles of water that could be converted to molecules on multiplying by Avogadro number. The set could be shown using dimensional analysis ascules are produced by the complete neutralization of one mole of phosphoric acid and potassium hydroxide.
