How do I find the empirical formula for aluminium selenide?

You have to have some data, such as masses, or percent: Empirical means it was measured.

The empirical formula for aluminium selenide is the same as it's molecular formula; Al2Se3.
The empirical formula requires both or all atom quantities to be divided by the same number, so Al9Se3 would become Al3Se, but Al7Se3 would stay the same.

    Hi, Can someone please help??? looking for the empirical formula for Aliminium selenide if Se has a valency of -2 and aliminium 3! Thanks :) Wouldn't it be Al2Se3? Al is +3 and 3 x 2 = +6. Se is -2 and -2 x 3 = -6 And +6 - 6 = 0
