Use the reaction given below to solve the problem that follows: Calculate the mass in grams of aluminum oxide produced by the reaction of 15.0 g of aluminum metal. [ ]grams Al2O3

4 Al + 3 O2 --> 2 Al2O3

**Your answer should be written as XX. X

 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal

Explanation:

To calculate the moles :

The balanced chemical equuation is:

According to stoichiometry :

4 moles of produce == 2 moles of

Thus 0.556 moles of will produce=  of

Mass of

Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.
