How do you do stoichiometry problems. Can you give me an easy way to set up the steps and solve them?

Question

rogue · Answer

Stoichiometry is pretty much all about converting. You have to set up the problems in a way the units cancel out, i.e. dimensional analysis.

xishem · Answer

You start with a value you know and use conversion factors to get to a value you want.

Here is a simple problem:
A sample contains 27.1 g of calcium oxide.  How many moles of calcium oxide are in the sample?

xishem · Answer

However, 90% of the difficulty of stoichiometry problems come from determining what the problem means.

As you solve more and more problems, you'll learn to first categorize a problem, then conjure up the algorithm you need to solve it, and then actually the solve the problem and report the answer.
