WebDec 17, 2024 · So pure phosphoric acid can be made with 142 / 196 = 72.4 % P X 2 O X 5. As a consequence, a solution containing 75 % phosphoric acid can be made with 0.75 · 0.72.4 % = 54.3 % P X 2 O X 5. If now you want to dilute it to get a solution containing 4.7 % P X 2 O X 5, you have to take 4.7 / 54.3 = 8.65 % of your initial solution.
