Quantitative information: one unit of the compound contains three calcium atoms and two phosphate ions. Phosphorus pentoxide is a chemical compound with molecular formula P 4 O 10 (with its common name derived from its empirical formula, P 2 O 5). Because of its instability, white phosphorus is typically stored under water, in which it is barely soluble. "Moles of phosphorus ATOMS" = (23.0*g)/(31.00*g*mol^-1) = 0.742*mol. This molecule was suggested by a reader. Produces phosphoric acid and hydrogen sulfide, a toxic flammable gas with water. It is generally found as a dimer of P2O5 that’s why it is known as phosphorous pentoxide. Let ACS help you navigate your career journey with tools, personal coaching and networking.
