Stoichiometry-1: Mole to Mole

Directions:  Answer the following questions using the Factor label Method.  You must check to see that the chemical equation is balanced before using it. Do NOT forget your units on ALL numbers! Use the correct number of significant digits in your answer.

1) Using the following equation, calculate the number of moles of silver produced when 5.0 moles of aluminum is reacted. 

Al  +      AgNO₃ à     Al(NO₃) ₃  +      Ag

 

2) Using the following equation, calculate the number of moles of sodium nitrate produced when 3 moles of sodium sulfate is reacted. 

Ba(NO₃) ₂  +     Na₂SO₄ à     BaSO₄  +       NaNO₃

 

3) If 10.0 moles of H₂ are produced, how many moles of water must have been reacted?

  Al  +       NaOH +      H₂O à      NaAl(OH) ₄  +      H₂

 

4) How many moles of carbon dioxide can be produced by reacting 12 moles of carbon?

     Cr₂O₃ +      C à      Cr +      CO₂

 

5) How many moles of octane are required to react with 100 moles of oxygen gas?

     C₈H₁₈  +       O₂ à       CO₂  +       H₂O

 

6) How many moles of calcium phosphate are required to react completely with 3 moles of silicon dioxide?

Ca₃(PO₄) ₂ +       SiO₂ +      C à       CaSiO₃ +       CO +      P

 

7) If a company needs to produce 13.5 moles of KI, how many moles of glucose will be required?

      KIO₄  +       C₆H₁₂O₆ à        CO₂  +        H₂O  +        KI

 

8)  How many moles of aluminum are required to react with 11.1 moles of iron(III) oxide?

       Al  +    Fe₂O₃ à        Fe  +     Al₂O₃

 

9) How many moles of nickel(II) hydroxide will be produced if 20.0 moles of sodium hydroxide are reacted with nickel(II) nitrate?

Ni(NO₃) ₂  +       NaOH à      Ni(OH) ₂  +        NaNO₃

 

10) How many moles of octane are required to react completely with 50.0 moles of ammonium nitrate to produce nitrogen gas, carbon dioxide and water?

(let me help you with this one) 25NH₄NO₃  +  C₈H₁₈ à  25N₂  +  8CO₂  +  59H₂O
