When a 426 mg sample of the amino acid is burned, 631 mg of carbon dioxide and 301 mg of water are formed.
In a separate observation, the same amount of sample of amino acid is boiled in excess sulfuric acid, then neutralized with sodium hydroxide to convert all of the nitrogen into NH3. The NH3 is then titrated with HCl :
a total of 174 mg of HCl is required to consume all of the NH3.
(The balanced titration reaction is: NH3 + HCl --> NH4Cl ).
From this information, determine the empirical formula of this amino acid.
It determines the empirical formula of the amino acid. The response is detailed and received a '5/5' fro the student who posted the question originally.
