Answer;
160 g
Explanation;
1 mole of a compound contains a mass equivalent to the relative formula mass of that particular compound.
the formula of iron oxide is Fe2O3
R.A.M of Iron = 56 , while that of oxygen is 16
RFM = (56 ×2) + (16 ×3)
= 112 + 48
= 160
Therefore, 1 mole of Iron oxide contains 160 g
