The balanced equation for the reaction is: 2Ti + 3Cl2 → 2TiCl3 Using stoichiometry, we can calculate the theoretical yield of TiCl3 from 2.02 g of Ti: 2.02 g Ti × (1 mol Ti/47.87 g Ti) × (2 mol TiCl3/2 mol Ti) × (163.84 g TiCl3/1 mol TiCl3) = 7.47 g TiCl3 (theoretical yield) The actual yield obtained is 6.50 g, which is 87.0% of the theoretical yield. Therefore, the empirical formula of the compound is TiCl₃. (Note: the compound is most likely TiCl3, which has a known empirical formula, but we cannot assume that without further information).
