Determine the emp
Percentage of Iron in the oxide = 69.9%
Percentage of oxygen in the oxide = 30.1%
To determine the empirical formula of iron oxide, we need to find the simplest whole number ratio.
Simplest molar ratio of iron to oxygen:
= 1.25: 1.88
= 1: 1.5
for converting above ratio in the whole number ratio by 2,we will get
= 2: 3
The mole ratio of the element is represented by subscripts in empirical formula.
Therefore, the empirical formula for iron oxide is Fe2O3.
