NH3+HCl--> NH4Cl
1mole of HCl reacts with 1mole of NH3
36.5 gm of HCl reacts with 17 gm of NH3
5.99 gm of HCl will react with (17/36.5)*5.99
=2.8 gm of NH3
From 36.5 gm of HCl 53.5 gm of NH4Cl is formed
Therefore from 5.99 gm of HCl (53.5/36.5)*5.99
=8.8 gm of NH4Cl will form
Remaining NH3= (5.99-2.8)gm
=3.19gm
=0.2mole
NH3 is the only gas remaining in the flask.
Therefore the pressure of the gas is, P= nRT/V
=(0. 2*0.082*298) /2
=2.44 atm-pr
