an open manometer is filled with mercury and connected to a container of chlorine gas. the level of mercury is 135.0mm higher in the arm connected to the gas. air pressure is 99.0 KPa. what is the pressure, in kilopascals, of the chlorine gas?

Question

an open manometer is filled with mercury and connected to a container of chlorine gas. the level of mercury is 135.0mm higher in the  arm connected to the gas. air pressure is 99.0 KPa. what is the pressure, in kilopascals, of the chlorine gas?
