Glycine is an amino acid made up of hydrogen, carbon, oxygen, and the nitrogen atoms. Combustion of a .2036 gram sample gives the 1.00 atm and.122 g of water and 132.9mL of CO2 at 25oC. Calculate the percentages of carbon and hydrogen in glycine? Another sample of glycine weighing .25grams is treated in such a way that all the nitrogen atoms are converted to N2(g); this gas has a volume of 40.8 mL at the 25oC and 1.00 atm. Estimate the percentage of nitrogen glycine? Find out the empirical formula of glycine?
