P₄ + 3 O₂ -> P₄O₆ 

What is the limiting reactant is 12 moles of P₄ react with 15 moles of O₂?

• P₄

• O₂

• P₄O₆ 

• none of the above

Place the steps of solving for amount of excess reactant left

• determine limiting reactant

• set up and calculate a gram to gram conversion from limiting to excess reactant

• find the given grams of the excess reactant

• subtract the answer of your calculation from the given grams
