Molar Mass of Al: 2(27.0g/mol) = 54.0g/mol
Molar Mass of O: 3(16.0g/mol) = 48.0g/mol
Molar Mass of compound: 102.0g.mol
(54.0g/mol / 102.0g/mol) x 100% = 52.9%

Is crushing an aluminum can a physical irreversible change?
Yes. Physical change is when you change the appearance but not the actual object. Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
