SO3 is Molecular Weight 80. 40.0g is thus 0.5 moles so there are 3 x 0.5 x 6.022 x 1023 atoms of oxygen = 9.033 x 1023 oxygen atoms in 40.0 g of SO3. Wiki User. WebFirst, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams. ims returns form
