Using the atomic weights of iron, phosphorus and oxygen the molar mass of the molecule can be found. The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Pages 3. Molar mass = (55.845 x 3) + ( 2 x 30.97) + ( 8 x 16) = 167.535 + 61.94 + 128 =357.475 g/mol % Fe = 167.535 x … When converting from moles to molecules, you multiply the number of moles by 6.02 x 10^23. the molar mass of a substance is the mass in grams that a mole of atoms - #6.02 * 10^23# atoms - has. When convertig from molecules to moles, you divide by that same number. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d 6 4s 2. It is structure is monoclinic and in general, it is formed by three cations Fe 2+ and two anions PO 4 3-that are surrounded by eight water molecules.
