For the calculation of number of moles of HCl
that is produced by 2.73 moles of H₂.
Considering the reaction shown below:
H₂ + Cl₂------->2HCl
This can be seen from the reaction that 1 mole of H₂ produce=2 mole of HCl
So , 2.73 mole of H_{2} will produce= 2.73\times 2 mole of HCl
That is 2.73 mole of H_{2} will produce= 5.46 mole of HCl
So 5.46 mole of HCl will be produced by 2.73 mole of H_{2}
