HELLO ROHIT,
Molecular weight of H2 = 2 g/mol
Molecular weight of D2 = 2X2 = 4 g/mol
step 1
22.4L of H2 weighs = gm molecular weight of H2
= 2gm => 1mol
So 2.24L of H2 weighs = 0.2gm => 0.1 mol
step 2
22.4L D2 weighs = gm molecular weight of D2
= 4gm => 1mol
So 1.12L of D2 weighs = 4g X 1.12L/22.4L
= 0.2gm
Now,
0.2gm = 0.2g/4g/mol
= 0.05 mol
this is the simplest way to solve this question
THANK YOU
