P is +3, O is -2

Zero. Phosphorus will not trade electrons with itself.
From every two atoms of P, one molecule of P2O5 is formed. The relative formula mass of two atoms of P (phosphorous) is 62, whereas for one molecule of P2O5 it is 142. The mass of P2O5 formed is therefore 142/62 times the mass of P we started with. This comes out to 286.3g (to one decimal place).
Molar mass of P2O5 is 142gmol-1. You need 17.2 moles of p.
7 - 9.5% P; 16 to 22% P2O5 this is the phosphorous content in superphosphate
There is no oxidation number because oxidation number only applies to compounds with oxygen like MnO4 2- in which Mn has an oxidation number of 6
5
There are two oxidation numbers. P shows +5 oxidation number.
The oxidation number of P2O5 is Phisphorus +5, Oxygen -2.
The correct chemical formula should be P2O5 or P4O10 (its dimer) and not P3O10 (as originally asked in the question). The oxidation numbers are -2 for each O +5 for each P
Zero. Phosphorus will not trade electrons with itself.
+5. The formula of phosphorus pentoxe is P2O5. (It should be called diphosphorus pentoxide but historically they got it wrong). O is -2 so P has to be +5
P is phosphorus, O is oxygen P2O5 molecules have two (di-) P atoms, and five (pent-) O atoms, so the name of the compound is diphosphorus pentoxide.
From every two atoms of P, one molecule of P2O5 is formed. The relative formula mass of two atoms of P (phosphorous) is 62, whereas for one molecule of P2O5 it is 142. The mass of P2O5 formed is therefore 142/62 times the mass of P we started with. This comes out to 286.3g (to one decimal place).
+5 oxidation state
There is no compound by the formula PO. There is element, polonium with the symbol, Po, and in elemental form, Po has zero oxidation state.
Mg = +2 oxidation state P = +5 oxidation state O = -2 oxidation state
O = -2 oxidation state P = +5 oxidation state
