An organic compound was synthesized & a sample of it was analyzed & found to contain only C, H, N, O, & Cl. It was observed that when a 0.150g sample of the compound was burned it produced 0.138g CO2 & 0.0556g H2O. All the nitrogen in a different 0.200g sample of the compound was converted to NH3, which was found to weigh 0.0238g. Finally the chlorine in a 0.125g sample of the compound was converted to CL and by reacting it with AgNO3, all the chlorine was recovered as the solid AgCl. The AgCl, when dried was found to weigh 0.251g. What is the empirical formula of this compound?
