I understand that the name derives from the empirical formula; however, I do not understand why it does not exist as $\ce{P2O5}$. Is there a compound that exists with this as its molecular formula?
So, what happens is that phosphorus pentoxide is very powerful dehydrating agent and can rip off water molecules from compounds. Phosphorus pentoxide can dehydrate nitric acid to form its anhydride, dinitrogen pentoxide. $$\ce {2HNO3 -> [P2O5] [- H2O] N2O5}$$ Why dinitrogen pentoxide is not used as a dehydrating agent? My take on this is that hydrolysis of dinitrogen pentoxide is not that ...

$\ce {P2O5}$ content is useful as it is the phosphorous content that a scientist often cares about when using phosphoric acids. This might seem silly given that as you pointed out anything from $0-70% \ \ce {P2O5}$ could just be expressed as a percentage of $\ce {H3PO4}$ but there are times when a higher $\ce {P2O5}$ concentration is desired. For example polyphosphoric acids are useful ...
