An Unknown compound contains only carbon, hydrogen, nitrogen, and oxygen (C, H, N, & O). Complete combustion of 2.478 g of pure compound in pure oxygen produced 5.943 g CO2, 1.498 g H2O, and 0.210 g N2. What is the empirical formula?

An organic compound containing only C, H, and possibly O was subjected to combustion analysis. Asample weighing 0.8697 g yielded 1.593 g CO2 and 0.782 g H2O. What is the empirical formula of thecompound?

4. Quinone, which is used in the dye industry and in photography, is an organic compound containing only C, H, and O. What is the empirical formula of the compound if you find that 0.105 g of the compound gives 0.257 g of CO2 and 0.0350 g of H20 when burned completely? Given a molecular weight of approximately 108 g/mol, what is its molecular formula?

8) Camphor is an organic compound extracted from the camphor laurel tree. Its strong aroma makes it a common ingredient in many cooking recipes and perfumes. It contains C, H, and O. The combustion analysis of an 8.006 g sample of camphor affords 23.136 g of carbon dioxide and 7.579 g of water. The molecular weight of camphor is between 150 and 160 g.mol¹. a. What is the mass of carbon originally present in the tartaric acid sample?  b. What is the mass of hydrogen originally present in the tartaric acid sample?  C. What is the mass percentage of C, H and O in tartaric acid?  d. What is the empirical formula of tartaric acid?
