Reactions: Email This BlogThis! Phosphorus pentoxide is a chemical compound with molecular formula P4O10 (with its common name derived from its empirical formula, P2O5). Weak van der Waals forces hold these molecules together in a hexagonal lattice (However, in spite of the high symmetry of the molecules, the crystal packing is not a close packing[2]). This form can be made by condensing the vapor of phosphorus pentoxide rapidly, and the result is an extremely hygroscopic solid.[4]. In the thermal process, the phosphorus pentoxide obtained by burning white phosphorus was dissolved in dilute phosphoric acid to produce concentrated acid. Answer to: Calculate the mass of diphosphorus pentoxide (P2O5) which can be obtained by burning 25.0 g of phosphorus.

You can do the reverse unit conversion from %mass = [(mass PO4)/(mass of formula)] X 100 Then start with 1.00g sample and multiply by the higher, lower, unknown relation). [4] The metastable orthorhombic "O"-form (density 2.72 g/cm3, melting point 562 °C) adopts a layered structure consisting of interconnected P6O6 rings, not unlike the structure adopted by certain polysilicates. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. [1][5] The remaining polymorph is a glass or amorphous form; it can be made by fusing any of the others. [3] It is closely related to the corresponding anhydride of phosphorous acid, P4O6. These relative weights computed from the chemical equation are sometimes called equation weights. Please enable Javascript to use Use this page to learn how to convert between grams P2O5 and mole. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.
