in the reaction of aluminum metal and oxygen gas to make aluminum oxide, how many moles of aluminum will react with 0.80 grams o2?


Now, let's examine the outcome of the reaction between 6.38 moles of O2 and 9.15 moles of Al. Through simple calculation, we can derive the ratio of aluminum to oxygen which is 9.15/6.38, giving us a value of 1.434. This ratio indicates that all oxygen is utilized prior to the aluminum during the reaction, thus leaving unreacted aluminum as the final product. With this information in mind, we can approximate that the number of moles of Al2O3 generated amounts to approximately 4.25 moles.
