Oxides of virtually every element are known. Bromine, for example, forms several oxides when treated with ozone. Suppose you allow 1.550 g of bromine, Br2, to react with ozone and obtain 2.326 g of BrxOy. What is the formula of the product?

(1.550 g Br) / (79.904 g Br/mol) = 0.019398 mol Br (2.326 g compound) - (1.550 g Br) = 0.776 g O (0.776 g O) / (15.99943 g O/mol) = 0.048502 mol O (0.048501 mol O) / (0.019398 mol Br) = 2.500 So the ratio of O to Br is 5 to 2, and the formula is Br2O5.
