There is a lot more a chemistry student can do with numbers beside balance equations. A great chemistry student must be comfortable converting between different mass...

This is it! Here is the entire course IN ORDER!
There are few concepts more important in introductory chemistry than the mole. Really, it’s nothing more than a glorified ‘Chemist’s Dozen’, but...
Determining the molar mass of an entire compound is only slightly tougher than doing the same for a single atom. The real work comes in when you want to properly show...
Once you have a molar mass, it is not a big stretch to breakdown the mass percent of each constituent element. Intrigued? Take a look.

Composition Mathematics: Determining Empirical Formula From Percent Composition
So you’ve determined a percent composition from a compound’s formula. Big deal. Now it’d be something if you could determine an empirical formula from...

Composition Mathematics: Determining Molecular Formula From Percent Composition
You can find molar masses, percent compositions, and empirical formulas from those percent compositions. What’s left? Well, it’s one thing to determine the...
Stoichiometry is the ultimate tool of the chemistry student. Not unlike Daniel in the Karate Kid, you will take all of the disparate skills you’ve learned so far...
So let’s take a look at a classic stoichiometry problem. We’ll start with grams of one substance in a chemical reaction and work through to the equivalent...
Life’s not perfect. You run out of milk for your cereal. There is no bread left for your sandwich. In real life, as in chemistry, we constantly deal with the...
One footnote to the whole stoichiometry thing is the concept of percent yields. Though you may theoretically predict a certain amount on paper, what you actually get can...
