General Chem question??please help!?

A mixture known to contain AlBr3 and CaBr2 was analyzed by reaction with AgNo3 to precipitate all of the bromide ion as AgBr. If a 2.0143 g sample of the mixture yields 4.0034 g of AgBr, what is the weight percent of AlBr3 in the mixture?

The CaBr2 will generate AgBr and you can determine the amount of CaBr2 in the mix .

However we do not know how much AlBr3 we have from the data given

Have you missed something?
