Some of the information on this blog was taken from "Solving Problems in Chemistry" by Gary K. Himes. It helped me to finally understand mole concept and how to balance equations properly. I hope that it helps you as much as it helps me.
I find that rewriting it makes it easier to remember. So I recommend reading and rewriting what you see here. From page 1 to the end, that is, lesson 1 to the end.
