WebFormula weight (F.W.) is the sum of the atomic weights of all atoms in a given empirical formula. For example: sodium chloride (NaCl) has one atom of sodium (Na) and one atom of chlorine (Cl). The atomic weight of sodium is 22.99 g/mol and chlorine is 35.45 g/mol. Therefore, the formula weight of NaCl is 58.44 g/mol (22.99 g/mol + 35.45 g/mol). WebFor example, the molecular weight of polyethylene is calculated by multiplying the molecular weight of the repeating ethylene functional group times the number of units comprising the chain. Thus, for polyethylene ( Fig. 5 ), where the repeating unit contains two carbon atoms and four hydrogen atoms, the molecular weight is 28n, where n ...
