Empirical and Molecular Formula (With practice sheets!)

A couple of definitions I'm going to throw out there before we start:

Empirical Formula: The simplest ratio of atoms in a compound

Molecular Formula: The amount of atoms in a molecule, doesn't apply to ionic compounds.

So with those out of the way, how do we calculate the Empirical formula - and what does it look like?

Firstly, the empirical formula is the small numbers at the bottom of compounds. Its the 2 in CO2, the 4 in CH4 , but we need to know how to calculate this. However for thing such as S2Cl2, this would round down to just SCl due to the ratio being 1:1.

More will be explained in the video below.

Attached below are two worksheets that will help you practice calculating the Empirical Formula! Enjoyed this? Why not send it to one of your friends so they can understand something in chemistry!
