10. An organic compound was synthesized and a sample of it was analyzed and found to contain only C, H, N, O, and Cl. It was observed that when a 0.150 g sample of the compound was burned, it produced 0.138 g of CO, and 0.0566 g of H,0. All the nitrogen in a different 0.200 g sample of the compound was converted to NH3, which was found to weigh 0.0238 g. Finally, the chlorine in a 0.125 g sample of the compound was converted to CI¯ and by reacting it with AgNO3, all the chlorine was recovered as AgCl. The AgCl, when dried, was found to weigh 0.251 g. a. Calculate the weight percent of each element in the compound. b. Determine the empirical formula for the compound.
