Dear student,

Use the concept of equivalents,

Kuchh bhi?
Which equivalents you are talking about...

Moles of N2 & H2 are combining
Post reaction, NH3 is dissolved; moles left are 6 for H2 & hence 9 for N2 (since 6 mole H2 must have combined with 2 moles N2)

15 Moles in 16.42 L of volume available for gases (rest occupied by 3.58 L of water)

P = nRT/V
= 22.5 atm
