Expert Answer:

 
Check the pressure entered at the required points in the figure.
If Patm is expressed as 760 mm of mercury, then additional pressure ' ρgh ' is 150 mm of mercury.
then pressure of trapped gas is ( 760 + 150 ) = 910 mm mercury
 
in terms of kPa :-    760 mm of mercury = 101.325 kPa ; hence 910 mm of mercury = (910/760)×101.325 = 121 kPa
