Answer 1

Răspuns:

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
