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

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

3 Step Problems Grams A  Grams B Grams A  Liters B Grams A  Moles A (use mm A) Mole Ratio bB/aA Moles B  Grams B (use mm B) Grams A  Liters B Moles B  Liters B Grams A  Particles of B Moles B Particles B Liters A  Grams B Liters A  Moles A Mole Ratio bB/aA Moles B  Grams B (use mm B) Particles A  Grams B Particles A  Moles A Liters A  Particles B Moles B Particles of B
