- Make sure you start with a balanced equation!
(It's hopeless otherwise!)
- Calculate all molecular weights;
write them under each substance
- Check to make sure that everything balances!
- Set up a proportion: each term needs
actual problem units on top (numerator)
and theoretical equation units
on the bottom (denominator)
- Solve the resulting equation (Multiply both sides
by the denominator under "x")

Procedure for all stoichiometry problems --- "unit conversion" method |
- Make sure you start with a balanced equation!
(It's hopeless otherwise!)
- Convert what you know into moles (using molecular weight or atomic weight)
- Convert "moles of.." what you know into "moles of.." what you want
- Convert moles into final units (using molecular weight or atomic weight)
