    Firstly, how can you obtain Al2O3 from Al? WRITE an equation linking the two substances.

    Then, you'll see how many moles of Al react to form Al2O3.

    Find the number of moles, in 15.0g of Al. Depending on how many moles of Al2O3 produced per mole of Al, you'll have the number of moles of Al2O3 produced from 15.0g of Al.

    Finally, using the relative formula mass of Al2O3, you can have the mass of the Al2O3 produced.

    If you need more help, post where you can get to, and we'll see what we can do.
