the tin is converted to the oxide use the data table below to determine

A sample of tin (Sn) is heated in air to form a tin oxide. Assuming all of the tin is converted to the oxide use the data table below to determine the empirical formula of the tin oxide formed. mass of crucible = 31.50 g mass of crucible tin (before heating) = 33.40 g mass of crucible tin (after heating) = 33.91 g
