One method of analyzing amino acids is the van slyke method. the characteristic aminogroups (nh2) in protein material are allowed to react with nitrous acid, hno2, to form n2 gas. from the volume of the gas, the amount of amino acid can be determined. a 0.0604‑g sample of a biological sample containing glycine, ch2(nh2)cooh, was analyzed by the van slyke method and yielded 3.70 ml of n2 collected over water at a pressure of 735 torr and 29˚c. what was the percentage of glycine in the sample?
