Reaction Stoichiometry Mass A to Mass B

The Key to Reaction Conversions Mass A  Mole A  Mole B  Mass B

Mass A  Mole A  Mole B  Mass B Aluminum metal and chlorine gas react to produce aluminum chloride.

Mass A  Mole A  Mole B  Mass B 2 Al (s) + 3 Cl2 (g)  2 AlCl3 a. How many moles of chlorine gas are needed to react with 1.5 moles of aluminum?

Mass A  Mole A  Mole B  Mass B 2 Al (s) + 3 Cl2 (g)  2 AlCl3 b. How many grams of AlCl3 will be produced if 2.50 moles of Al react?

Mass A  Mole A  Mole B  Mass B 2 Al (s) + 3 Cl2 (g)  2 AlCl3 c. How many moles of Cl2 must react to produce 12.3 g of AlCl3?

Mass A  Mole A  Mole B  Mass B 2 Al (s) + 3 Cl2 (g)  2 AlCl3 d. If 17 grams of aluminum react, how many grams of aluminum chloride will be produced?
