Determine the total nitrogen concentration in mg/L of a water sample containing 1.3 mg/L ammonia, 0.25 mg/L nitrite, 15.1 mg/L nitrate, and 0.9 mg/L organic nitrogen.

Homework Answers

Answer #1

nitrogen concentration = (1.3/17 )*14 = 1.07 mg/L

                        = (0.25/46)*14 = 0.076 mg /L

                        = (15.1/62)*14 = 3.407 mg/L

                      = 0.9 mg/l

total Nitrogen = 0.9+3.407+0.076+1.07 = 5.453 mg/L
