Tin reacts with nitric acid in a crucible to form tin nitrate. Heating the product of this reaction generates nitrogen dioxide, a brown gas, and tin oxide. Given the following experimental results, what is the formula of the tin oxide formed?

Mass of crucible = 13.457 g

Mass of crucible + tin = 14.710 g

Mass of crucible after heating = 15.048 g
