Explanation:
Given that the formula of the compound is Fe2O3, if a coefficient of 2 is placed in front of the formula, that is, if we write 2Fe2O3 . Then;
The number of Fe atoms becomes 2 *2 = 4
The number of oxygen atoms becomes 2*3 = 6
That is why the total number of iron atoms were written down as 4.
A)1.75×3 moles of carbon monoxide
