In a previous problem, the empirical formula of a compound of phosphorus and oxygen was found to be p2o5. experimentation shows that the molar mass of this compound is 283.89g/mol. what is the compounds molecular formula?
the empirical formula for the compound is - P₂O₅ the empirical formula is the simplest ratio of whole numbers of components in a compound. molecular formula is the actual ratio of components in a compound. we have to first find the number of empirical units in the molecular formula molecular mass - 283.89 g/mol mass of empirical formula - 283.8 g number of empirical units - 283.89 g/mol / 283.8 g number of empirical units - 1.000 therefore empirical formula = molecular formula molecular formula - P₂O₅
