write pressure equation for both tubes.

Explanation:

write pressure equation for the two tubes :
as we know , pressure at same height is same .
# P_a - rho*g*(13.2-3.5)/100 = P_g #
#P_a - pressure due to atmosphere #
# P_g - pressure due to the gas #
#rho - density of liquid in the tube #
putting the values in the above equation , you can obtain the pressure exerted by the gas in the column BC .
