When 22.4 litres of H2(g) is mixed with 11.2 litres of Cl2(g), each at S.T.P, the moles of HCl(g) formed is equal to :-
The number of moles present in 11.2 litres of CO2 at S.T.P is:
One mole of a gas having a volume equal to 22.4 litres and at 1 atmospheric pressure in compressed isothermally so that its volume reduces to 11.2 litres. The work done in this process is
