WebFormula in Hill system is FeS2: Computing molar mass (molar weight) To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use: Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. Webthe balanced reaction will be 4FeS2+11O2 -> 2Fe2O3+8SO2. It is a redox reaction.Number of electrons gained =Number of electrons lost. 1 mole of FeS2 = (11/4) moles of O2. Each O atom takes 2 electrons for reduction. Therefore for 1 O2 molecule 4 electrons are absorbed for reduction. Therefore number of moles of electrons gained by O2 = (11/4)*4=11.
