Question

In ce cantitati de HCl, NH3 si CH4 se gaseste aceeasi cantitate de H ca in 12 moli de H2O ?

Answer 1

1 mol H2O......2 g H
12 moli H2O.......x g H        x = 24 g H
36,5 g HCl..........1 g H
a g HCl.............24 g H       a = 876 g HCl = 24 moli 
17 g NH3..........3 g H
b g NH3............24 g H       b = 136 g NH3 = 8 moli
16 g CH4...........4 g H
c g CH4............24 g H       c = 96 g CH4 = 6 moli
