How to define the empirical formula for water?
So how do you define the empirical formula?
I know for me, differentiating between the Empirical Formula and the Molecular Formula was always a point of confusion that often tripped me up.
Sometimes they were the same, sometimes they were not, but what determined this?
In this video, we break it all down, showing you exactly how to define the empirical formula for any compound you end up seeing on the day of your FE Exam.
Key Definition
What is the EMPIRICAL FORMULA?
The EMPIRICAL FORMULA of a chemical compound is the simplest positive integer ratio of atoms present in a given compound.
An EMPIRICAL FORMULA does not necessarily represent the actual number of atoms present in each molecule of a compound; it represents only the ratio between those numbers.
The actual number of atoms of each element that occur in the smallest freely existing unit or molecule of the compound is expressed by the MOLECULAR FORMULA of the compound.
The MOLECULAR FORMULA of a compound may be the EMPIRICAL FORMULA, or it may be a multiple of the EMPIRICAL FORMULA.
So how can you define the empirical formula for any compound?
Check out the video and see how we can go about solving this type of problem in the most efficient manner.
