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.
WebSolution Verified by Toppr Correct option is D) Equivalent of O 2 is 8 gm/equivalent because in a electrode reaction 4 moles of electrons deposit on one mole of O 2. Therefore, 1 mole of O 2 will be equal to equivalent oxygen. ∴ Correct answer is D.
