Calculation
Total N % by weight = 0.14 (V – U) x 100x 100 --------------------------------- 0.5x 5X1000
1 ml of 0.01N H2SO4 = 0.14 mg of N. U = Volume in ml of H2SO4 solution used to neutralize the ammonia liberated from blank solution V = Volume in ml of H2SO4 solution used to neutralize the ammonia liberated from the sample solution W= Weight of (in g) material taken for the test. Total protein % x N content X 6.25 |
