Therefore oxygen retained in the body = 19-12.5 = 6.5 5000/100 = 50cm3 50cm3*6.5cm3 = 325cm3, hence the answer. Hope this...

Equation being formed is: 2Mg + O2 --> 2MgO 4Al +3O2 ---> 2Al2O3 S + O2 ---> SO2 Simplifying them since you need one mole of reactant, you'll get: Mg + 0.5O2 ---> MgO Al + 0.75O2 ---> 0.5Al2O3 S + 1O2...
