4moli Cl2
4moli xmoli
H2 + Cl2= 2 HCl
1mol 2moli
x= 4 .2 = 8 moli HCl
MHCl= 1 + 35,5= 36,5------> 36,5g/moli
m= n . M
m= 8 moli . 36,5=292gHCl
4moli ymoli
3Cl2 +2 Fe=2 FeCl3
3moli 2moli
y= 4.2 : 3=2,66moli FeCl3
M= 56 + 3.35,5=162,5------> 162,5g/moli
m= 2,66moli . 162,5 g/moli =432,25 g FeCL3
4moli zmoli
Cl2 +2 Li = 2LiCl
1mol 2moli
z= 4.2=8 moli LiCl
M= 7 + 35,5=42,5-----> 42,5g/moli
m= 8moli. 42,5g/moli=340gLiCl
4moli amoli
Ba + Cl2= BaCl2
1mol 1mol
a= 4moli BaCl2
M= 137 + 2.35,5=208----> 208g/moli
m=4moli . 208 g/moli=832gBaCl2
