The partial pressure of the gas collected is 204.16 kPa.

Explanation:

Since the gas must bubble through the water before being collected, it becomes saturated with water vapour.

When the water levels inside and outside the container are equal, the #"pressure of the gas + the pressure of the water vapour = the barometric pressure"#

The vapour pressure #p_text(vap)# of water at 25 °C is 3.1690 kPa.

∴ #p_text(gas) = p_text(bar) - p_text(vap) = "207.33 kPa - 3.1690 kPa" = "204.16 kPa"#
