1. CALCULAR MASA MOLECULAR:
H: 1 x 1,007 g = 1,007 g/mol
N: 1 x 14,006 g = 14,006 g/mol
O: 3 x 16 g = 48 g/mol
Mm = 63,013 g/mol
2. Calcular % de cada elemento
H: 1 g ----- 63,013 g
X ----- 100%
X = 1 g x 100% = 1,587 % de H
63,013 g
N: 14,006 g ----- 63,013 g
X ----- 100%
X = 14,006 g x 100% = 22,22 % de N
63,013 g
O: 48 g ----- 63,013 g
X ----- 100%
X = 48 g x 100% = 76,174 % de O
63,013 g
