Titаnium оxide is widely used аs а white pigment in paints, plastics, and paper. It is alsо the active ingredient in many mineral-based sunscreens because it reflects and scatters ultraviоlet (UV) light. Titanium oxide is produced by reacting titanium metal with oxygen gas. Given the experimental data in the table below, determine the empirical formula of titanium dioxide. The molar mass of titanium is 47.87 g/mol, and the molar mass of oxygen is 16.00 g/mol. Mass of empty crucible 63.428 g Mass of crucible with titanium before reaction 68.694 g Mass of crucible after the reaction 72.214 g Enter the empirical formula using the element symbols and numbers (e.g. A2B3)
