N#2 19 c.c. soln contains 12 grams of NH4NO3
2 10 c.c. of 3.85 M soln of MnCl2
Molarity of N = 16M
Molarity of Mn [illegible] = 2M
N#3 18 c.c. soln contains 12.5 grams NH4NO3
10 c.c. of 3.8512 M soln of MnCl2
Molarity of N = 17.4 M
Mn [illegible] = 1 M
N#4 12.5 grams NH4NO3 in 18 cc H20 ; 0.2 M MnNO3
N
A 1.948 g Cr(NO3)3 9 H2O 1.948 x 42/400.2= 0.204 g
B 1.832 g NH4NO3 1.832x28/80 = 0.64 g
C 2.240 g NH3 2.240x14/17 = 1.84 g
Ration of A to (B+C) = 0.204/2.48 = 0.082
Total nitrogen content in NH3 = 2.18 g.
Total nitrogen content = 2.64 g.
Ratio = 2.18/2.64 = 0.825
0.825/15 = 0.055
