Introducing...Stoichiometry!!

Today we looked at the relationship between mols of reactants and products, stoichiometry. For any stoichiometry problems, there are a logical set of steps to follow:
1. Balance the equation.
2. Convert the quantity you know into mols.
3. Convert mols of what you know to "mols of interest" using the coefficients (ratios) in the balanced equation.
4. Convert "mols of interest" into a useful number. That useful number might be a mass or a volume or a number of other things, it all depends upon the problem.

We looked at a precipitation reaction and an acid-base reaction today, we'll look at a couple other reactions on Wednesday.

There is a new MasteringChemistry assignment posted, due Sept. 28th.
