M,H2=2g/mol
M,Cl2=71g/mol
Vm=22,4 l/mol c.n.
1.V= niuxVm=1molx22,4 l/mol=22,4 l
m= 1molx2g/mol= 2g.....................................................a
2. niu=V/Vm= 22,4 l/22,4l/mol=1mol
m=1molx71g/mol=71g....................................................b
3. niu=V/Vm= 44,8 l/22,4 l/mol=2mol
m= 2molx71g/mol=142g.................................................d
4. 1molH2 c.n. V=22,4 l/mol si m= 2g......................c, a
