According to Gay-Lussac's law, 3 volumes of H2 will give 2 vol. of NH3 .
∴67.2L‌of‌H2 will give =

2×67.2

3

=44.8L‌of‌NH3
At the same time,
3 vol. of H2 will react =1 vol. of N2.
∴67.2L of H2 will react =

1

3

×67.2L of N2 =22.4L of N2
67.2L of H2 and 22.4L of N2 are required to form 34g of NH3.
So, for 3.4g of NH3
6.72L and 2.24L of H2 and N2 gas are required respectively.
