How do you calculate P2O5 in phosphoric acid?
- Molar mass of P2O5 = 31 x 2 + 16 x 5 = 62 + 80 = 142.
- Molar mass of H3PO4 = 1 x 3 + 31 + 16 x4 = 3 + 31 + 64 = 98.
- P2O5 dissolves in water to form H3PO4 as per equation :
- P2O5 + 3 H20 = 2 H3PO4.
- 142 gm of P2O5 is equivalent to (98 x 2) gm of H3PO4.
- That is, 142 gm of P2O5 is equivalent to 196 gm of H3PO4.
Is P2O5 phosphoric acid?
Phosphorus pentoxide is a chemical compound with molecular formula P4O10 (with its common name derived from its empirical formula, P2O5). This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant and dehydrating agent.

How do you calculate P2O5?
To convert P to P2O5 multiply by 2.29. To convert K2O to K divide by 1.21.
How do you convert P2O5 to PO4?
The conversion factor from orthophosphate (PO4) to phosphorus pentoxide (P2O5) is 0.7473. This conversion is based on the molar mass ratio for the two compounds. For each PO4 molecule there is 1 phosphorus (P) atom whereas for each P2O5 molecule, there are 2 phosphorus (P) atoms.
What is percentage of P2O5 in H3PO4?
One hundred percent phosphoric acid contains 72.4% P2O5 as calculated from the formula weight ratio P2O5/H3PO4. Similarly, pyrophosphoric acid (H4P2O7) contains 79.8% P2O5 as calculated from the ratio P2O5/H4P2O7.
