**Problem 9: Determining the Empirical Formula**A 1.35 g sample of a substance containing carbon, hydrogen, nitrogen, and oxygen was burned to produce 0.810 g of water (H₂O) and 1.32 g of carbon dioxide (CO₂). In a separate reaction, all the nitrogen in 0.735 g of the substance was converted to ammonia (NH₃), resulting in 0.284 g of NH₃. Determine the empirical formula of the substance.**Analysis and Steps:**1. Calculate the moles of each element (C, H, N, and O) based on the given masses of products.2. Use the ratios derived from moles to determine the simplest whole-number ratio of atoms in the compound.3. Establish the empirical formula based on these ratios.

Total weight of the substance is 1.35 g The compound consists of C,H,O & N. Amount of H2O = 0.810 g Amount of CO2= 1.32 g Amount of NH3= 0.284 g Amount of Nitrogen = 0.735 g The empirical formula of the compound can be:CXHYNZOP → XCO2 + YH2O Amount of CO2 formed=1.32Moles of CO2 formed= 0.03 X= 0.03X= 0.030.0167X= 1.8amount of H2O formed= 0.810 gMoles of H2O formed= 0.045 Y= 0.045Y= 2.7Amount of NH3 formed= 0.284 gMoles of NH3 formed= 0.0167 z= 0.0167 Z= 1Amount of oxygen =1.32 +0.810 + 0.284 - 1.35 g=1.064 gMoles of O=0.133p= 8Empirical formula is :C2H2.7N1O8 C6H8N3O24
