Very impressive. in 3 minutes and 25 you taught me how to find empirical formulas. My teacher took two 50 minute classes to make us learn this and it was complicated for me. You saved my life, I have a chem test tomorrow! Thanks

I understand how you feel about teachers taking a long time to explain something that can be explained in minutes. The problem lies in the fact that school require teachers to teach a lesson for an hour or longer which can really confuse a person, especially when it can be explained in minutes rather than hours.
