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. WebBecause fluorine is much more electronegative than carbon, fluorine can better stabilize the negative charge in the \(F^−\) ion than carbon can stabilize the negative charge in the CH3− ion. ...
