The corresponding balanced reaction is:
𝐻2+𝐶𝑙2→2𝐻𝐶l
Again, 0.4gH2=

0.4

2

mol=0.2mol
7.1gCl2=

7.1

71

mol=0.1mol
So, Cl2 is the limiting reagent here.
Hence 0.2 moles of HCl will be formed.
Again, we need to find out the volume of HCl formed in the STP condition.
1 mol of a gas in STP occupies 22.7L
Thus, 0.2 mol of HCl will occupy =4.54L
