A 1.5000-g sample of cereals was analyzed for nitrogen using the
Kjeldahl procedure. The receiving flask contained 69 mL of 0.02 M
HCl. After the ammonia was collected, the solution was titrated
with 0 M NaOH, requiring 11.72 mL to reach the methyl red endpoint.
Calculate and percent protein in the sample (f=5.70). Ans. in 3
