Question

Calculate the mass of ferric oxide that will be obtained by complete oxidation of 2g of Fe. Atomic weight of Fe=56 u, O = 16 u [Ans: 2.86 g] PLEASE ANSWER WITH STEP BY STEP EXPLANATION .

Answer 1

Generally ferricoxide is obtained from Fe and O as Fe2O3
     so ,
      Fe2+O3- Fe2O3
       2g . atomic wt of Fe + 3g. atomic wt of O= WEIGHT OF Fe2O3
       in chemistry mass is very closer term to weight
     2.56 + 3.16=112+48
                      =160
   therefore mass of ferric oxide is 160 g but i dont know how to get 2.86g

Answer 2

Answer:

Explanation:

1994÷837=2.38g
