Aluminum bromide is produced by the reaction of aluminum metal with bromine liquid, according to the following balanced equation:

2 Al(s) + 3 Br2(l) → 2 AlBr3(aq)

If 10.0 grams of Al is added to 10.0 g of Br2, assuming the reaction has yielded 100% yield, calculate the mass (in grams) of AlBr3 produced in this reaction
