Stoichiometry is easy.
Every chemical equation has to be balanced.
If you have 3 carbon atoms on the left side of the equation, you must have 3 carbon atoms on the right side of the equation.
If you have 7 oxygen atoms on the left side of the equation, you must 7 oxygen atoms on the right side of the equation.
See the idea?
The objective is balance both sides. so, if I gave you the following problem and told you to fill in the coefficients...
(?#)H2 + (?#)O2 -------> (?#)H2O
You have to find the proper coefficients so that the number of atoms on each side is the same. In this case, the proper answer is 2H2 + O2 ->2H2O
(4 hydrogens, 2 oxygens on each side. The equation is balanced)*** Chemical Engineering Crew ***

If its just over introduction of stoichiometry
Think of it like solving a puzzle:
1.) Figure out what you are being asked
2.) Find out what you have (balanced chemical equation)
3.) Find out what you are missing
4.) Solve for what you are missing
If its Equilibrium reactions and such that are getting you, disregard above.

dude, stoichiometry is the easiest part of chem. If you have hard time with that, then all your chem prereqs for med school will be hell for you..:Foot Fetish Club:.

Da fuk OP? Just read the textbook........if it was only 2 days of class material then you can learn it fairly quickly. and its stoichiometry which is the easiest fukin chemistry problems
Seriously read the fuking textbook you lazy fuk, it sounds like youre just being a lazy fuk and dont want to read and just want the quick easy route. unless you have a reason that you dont have a textbook or cant read or something.
you should be reading the textbook anyways...if you cant do stoichemetry, then quit right now, if you dont have the drive to read the textbook for STOICHIOMETRY, then you wont have a chance doing much more advanced chemistry
look for chemistry by brown, its available on some torrent sites for download. then go to stoichemotry section and study away
