A sample of black mineral hematite, an oxide of iron found in many iron ores, contains 34.97g of iron and 15.03g of oxygen. what is the empirical formula of hematite?

The empirical formula : Fe₂O₃

Given

34.97g of Iron

15.03g of Oxygen

Required

The empirical formula

Solution

Mol ratio :

Fe(Iron) : 34.97 g : 56 g/mol = 0.624

O(Oxygen) : 15.03 g : 16 g/mol = 0.939

Divide by 0.624 :

Fe : O = 1 : 1.5

Fe : O = 2 : 3

its going to be mutualism cuz they both benefit from the relationship.
