Sevin, the commercial name for an insecticide used to protect crops such as cotton, vegetables, and fruit, is made from carbamic acid. A chemist analyzing a sample of carbamic acid finds 0.8007 g of carbon, 0.9333 g of nitrogen, 0.2016 g of hydrogen, and 2.133 g of oxygen. Determine the empirical formula for carbamic acid. 7. When 1.916 g of titanium is strongly heated in a stream of pure oxygen, a metal oxide sample weighing 3.196 g results. Calculate the empirical formula of the oxide.
