The molar mass of phosphoric acid is 97,99 g.
this means 0.6gm of phosphoric acid in 1000gm of water --------------------------------------- (the previous answer describes a mass percent) It means a 0.6 molal phosphoric acid (i.e. 0.6 mol hydrogen phosphate in 1 kg of water, which is roughly equivalent to 0.6 M phosphoric acid), though molality (mol/kg) is rarely used to denote concentration of acids. More common units are molarity M (mol/L) or normality n (mol/L of hydrogen ion generated).

To find the pH of completely ionized phosphoric acid, first determine the concentration of the hydronium ions (H3O+) by using the molarity of the phosphoric acid solution. Then, calculate the pH using the equation pH = -log[H3O+]. Since phosphoric acid has three dissociable protons, the pH would be dependent on the concentration of H3O+ from the complete ionization of the acid.
To prepare a 0.01M solution of phosphoric acid, you would weigh out the appropriate amount of phosphoric acid (H3PO4) based on its molecular weight and dissolve it in a known volume of water to reach a concentration of 0.01 moles per liter (Molarity). Make sure to use proper safety precautions while handling the acid and accurately measure the quantities to achieve the desired concentration.
To calculate the concentration of phosphoric acid, you need to know the volume of the solution containing phosphoric acid and the amount of phosphoric acid in moles present in the solution. By dividing the amount of phosphoric acid in moles by the volume of the solution in liters, you can calculate the concentration in units of moles per liter (Molarity).
Phosphoric Acid dissociates to give off 3H+ ions, meaning that one mole of Phosphoric acid reacts with three mols of sodium hydroxide. Using the equation n = c x v n = 0.1 x 0.05 =0.005 mols of OH ions in the solution therefore there are 0.005/3 = 0.00167 So the volume of phosphoric acid - v = n/c v = 0.00167/0.2 v = 0.00835 l = 8.4ml of Phosphoric Acid reacts completely with Sodium hydroxide

You can calculate the concentration of a phosphoric acid solution by determining the volume of sodium hydroxide needed to neutralize it in a titration. The molarity of the sodium hydroxide solution and the balanced chemical equation for the reaction will allow you to find the moles of phosphoric acid present, hence the concentration.
I don't think so.poly phosphoric acid and phosphoric acid have same moleculer structure.http://harvestchem.iblogger.org

Ortho-phosphoric acid is a specific form of phosphoric acid, where the phosphorus atom is bonded to three hydroxyl groups. Phosphoric acid, on the other hand, is a more general term that can refer to any acid containing phosphorus, including ortho-phosphoric acid, as well as pyrophosphoric acid and metaphosphoric acid.

To make a 9N (normal) Phosphoric Acid solution, you will need to know the concentration of your Phosphoric Acid. The formula to calculate the volume of Phosphoric Acid required is: Volume (in liters) = (Desired Normality * Equivalent Weight of Phosphoric Acid * Volume of Solution) / Concentration of Phosphoric Acid.
The chemical formula for phosphoric acid is H3PO4.
