Explicație:
2Al + 3Cl2 = 2AlCl3
n Al = 104/27 = 3,85 moli
1 mol Al...............2 moli AlCl3
3,85.....................x
x = 3,85*2 = 7,7 moli AlCl3
M AlCl3 = 27 + 3*35,5 = 133,5 g
m AlCl3 = 7,7*133,5 = 1027,95 g
--------------
2 moli Al.................3 moli Cl2
3,85........................y
y = 3,85*3/2 = 5,8 moli
