Equation stoichiometry is the culmination of many skills:

- Calculating Molar Mass
- Converting from Moles to Grams, Liters, & Particles
- Balancing Chemical Equations
- Finding the Mole Ratio
- Estimating Amounts and Planning Strategies

We put all of these skills together to solve mass to mass, mass to liters, and mass to molecules stoichoimetry problems.

- convert grams, liters, or molecules given in the problem to moles.
- use the
*mole ratio*to find moles of the desired quantity. - convert moles of the desired quantity to grams, liters, or molecules. This is the answer!

It is helpful to visualize two mole maps connected by the mole ratio to solve stoichiometry problems:

One way to find the the mole ratio is:

We get the coefficients for the mole ratio from the balanced equation.
