4Al + 3O2 → 2Al2O3How many moles of Al2O3 are produced when 0.78 mol of O2 reacts with Al?
Question
4Al + 3O2 → 2Al2O3
How many moles of Al2O3 are produced when 0.78 mol of O2 reacts with Al?
Solution
According to the balanced chemical equation, 3 moles of O2 produce 2 moles of Al2O3.
So, if 0.78 moles of O2 are reacted, the number of moles of Al2O3 produced can be calculated using the ratio from the balanced equation.
(0.78 moles O2) * (2 moles Al2O3 / 3 moles O2) = 0.52 moles Al2O3
So, 0.52 moles of Al2O3 are produced when 0.78 moles of O2 react with Al.
