Answer:
Explanation:
These atomic masses are approximate.
Find the mass of 1 mol Fe2O3
2*Fe = 2* 56 = 112
3*O = 3 * 16 = 48
Molar mass = 160
1 mol Fe2O3 = 160 grams
x mol Fe3O3 = 200
1/x = 160/200 Cross Multiply
160x = 200 Divide by 160
x = 200 / 160
x = 1.25 mols
When you do the problem (which you should), you will get a slightly different answer. Buy my answer should guide you about how to do the problem. Your periodic table will be more accurate than the one I have used.
