CHM110H5 Lecture Notes - Lecture 1: Ideal Gas Law, Dumas Method, Molar Mass
Document Summary
This experiment of organic analysis involves two separate parts. First part is to idenify the funcional group of the unknown compound by tesing it with reagents, and second part is to determine the molar mass of the unknown compound using dumas method. The purpose of this lab is to idenify the funcional group of an unknown compound. Dumas method was then used to determine the molar mass of the unknown compound. Finally by combining the results, we can idenify the unknown compound using the ideal gas law: From observaions recorded in data sheet, the funcional group of unknown was determined to be secondary alcohol. Given: (data collected from part 2 of the experiment) T=374k r=0. 0821 l atm/mol k m= 0. 329 g. M=0. 329g/ [(757 mm hg/760 mm hg) (0. 156l)/ (0. 0821 l atm/mol k) (374k)] With the molar mass of c=12. 01g/mol, o=16. 00g/mol, and h=1. 008g/mol, the unknown compound was determined to be 2-propanol, c3h8o.
