The partial pressure of the gas collected is 204.16 kPa.


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"#
