A 1.500-g sample of dried soil was analyzed for nitrogen using Kjeldahl procedure. The receiving flask contained 75.00 mL 0.04000 M HCI. After the ammonia was collected, the solution as titrated with 0.1000 M NaOH, requiring 23.70 m to reach the MR endpoint. Calculate the percent nitrogen in the sample.
