Web2 jan. 2024 · If you need to add a subscript to a polyatomic ion, enclose it in parentheses so it is clear the subscript applies to the entire ion and not to an individual atom. An example is aluminum sulfate, Al 2 (SO 4) 3. The parenthesis around the sulfate anion indicates three of the 2- sulfate ions are needed to balance 2 of the 3+ charged aluminum cations. WebAnswer (1 of 2): Molar mass of Al2O3 = 102 g/mol Amount of Al2O3 given = 200 g = 200/102 = 1.96 mol One formula unit of Al2O3 is supposed to contain 2 aluminium ions (Al^3+) and 3 oxide (O^2-) ions. So, 1 mole of Al2O3 should contain 2 moles of Al^2+ ions and 3 moles of O^2- ions. It means the...
