Heatwhat is the theoretical yield of aluminum oxide if 3.40 mol of aluminum metal is exposed to 2.85 mol of oxygen?

193.8 grams

Explanation:

As can be seen from the chemical equation, 2 moles of aluminium react with 3 moles of oxygen.

Thus 3.40 moles of aluminium react with= moles of oxygen.

But as the available amount of oxygen is less, oxygen is the limiting reagent as it limits the formation of product and aluminium is the excess reagent.

3 moles of oxygen react with 2 moles of aluminium

2.85 moles of oxygen react with= moles of aluminium.

3 moles of oxygen give 2 moles of

2.85 moles of oxygen give= moles of .
