The nitrogen and protein content of a 2.8391 g sample of milk was determined using Kjeldahl analysis. After digestion, the liberated NH3 was distilled in a flask containing 25.00 mL of standard 0.250 M HCI. Titration requires 31.65 ml of standard 0.100 M NaOH to reach the desired endpoint. Calculate the weight percent of N (FW-14.01) and protein in the sample of milk. Report values in 3 SF. % N = % % Protein
