Equalities for Stoichiometry

1 mole = molar mass (grams)

1 mole = 6.02 x 1023 particles

mole = mole through a molar ratio (coefficients)

3 of 10

Rules for Stoichiometry

  1. Start with the original quantity.
  2. Use map to fill out top of fractions. (pathway)
  3. Use equalities to fill in numbers one fraction at a time.
