Question

When 22.4 liters of H2 is mixed with 11.2 liters of Cl2 each at 273k at 1 atm. The moles of Hcl formed is equal to

Answer 1

1 mole of any gas at STP occupies 22.4 liters of volume

22.4 liters of H2 indicates 1 mole 
11.2 liters of Cl2 indicates 0.5 moles 

                       H2            +            CI2    -------------------->    2HCI
 initially  -         1                            0.5                                      0
 equilibrium  1 - 0.5                    0.5 - 0.5                              2(0.5)
                        0.5                            0                                       1

Therefore 1 mole of HCl is formed finally with 0.5 moles of H2 left unreacted.
