Ques. What should be the percentage of iron and dioxygen in a Fe2O3 molecule ?
(A) Fe- 69.9% and O2 - 30.1%
(B) Fe- 50% and O2 - 50%
(C) Fe- 57.7% and O2 - 42.3%
(D) Fe- 34% and O2 - 66%
Dear Student,
Please find below the solution of your asked query:
Please find below the solution of your asked query:
Molecular mass of Fe2O3 = 56 * 2 + 16 * 3 = 160
Mass of Iron = 112
% of Fe = Mass of Fe/Total mass * 100
= 70%
And the rest of the amount present is dioxygen i.e. 100 - 70 = 30%
Therefore, option (A) is correct.
Hope this information clears your doubts about the topic.
Keep asking!!
