Aluminum can preserve food and drinks longer than iron can. If oxygen combines with the iron the iron will rust and the food or drink inside will not be good to eat anymore and you will have to waste it.
1 mole ------------ 6.02 x10²³ molecules
? mole ----------- 1.505 x10²³ molecules
1.505x10²³ / 6.02x10²³ => 0.25 moles
