randament=mp . 100 : mt
Explicație:
-se afla masa de azot=mp
mp =597,33 . 96 :100=573,4368 g azot
573,4368g xg yg
N2 + 3 H2=2NH3
28g 3 .2g 2.17g
x=573,4368 .6 : 28=128,87 g hidrogen
n=128,87g : 2g/moli=64,435 moli H2
y=573,4368 . 34 :28=696,31 g NH3
n= 696,31 g : 17 g/moli=40,95 moli NH3
MNH3=14 +3=17----->17g/moli
