2. 1 Step Stoichiometry Questions If you need to put this on your periodic table.
Grams A  Moles A
Divide by molar mass A
Grams A  Moles A
Multiply by molar mass A
Moles A  Moles B
Mole Ratio x bB/aA
Moles A  Moles B
Mole Ratio x aA/bB
Particles A Moles A
Divide by Avogadro’s #
Particles A Moles A
Multiply by Avogadro’s #
Liter A  Moles A
Multiply by 22.4
Liter A Moles A
Divide by 22.4

3. 2 Step Stoichiometry Problems
Moles A  Grams B
Mole Ratio bB/aA
Mole B  Grams B (use molar mass B)
Moles A  Grams B
Grams B Moles B (use molar mass B)
Mole Ratio aA/bB
Moles A  Particles B
Moles A  Particles of A
Moles A  Particles B
Particles of B  Moles B
Mole Ratio aA/bB
Moles A Liters B
Mole Ratio bB/aA
Mole B Liters B
Moles A Liters B
Liters B  Mole B

4. 3 Step Problems Grams A  Grams B Grams A  Liters B
