FREE Expert Solution

We have to determine the empirical formula of the compound that contains 11.66 g iron and 5.01 g oxygen.


Empirical formula is a chemical formula that gives the relative proportions of elements in a compound but not the actual number of atoms of elements in a compound.


Empirical formula of a compound can be calculated using these steps:

Step 1: Find the masses of elements in the compound.

Step 2: Find the percentages of elements in the compound.

Step 3: Dividing the percentages of elements by their average atomic masses.

Step 4: Dividing the obtained numbers by the smallest number among them and rounding off to the nearest whole numbers to get the empirical formula.
