If the atmospheric pressure is 0.993 atm and the height of the water column after the reaction occurs is 16.5 cm, what is the total pressure of the gas in the eudiometer?

Solution

atmosphereic pressure = 0.993 atm

height = 16.5 cm

total pressure = Patm + d g h

                       = 0.993 + 0.088 x 9.81 x 16.5 x 10^-2

                       = 0.993 + 0.1424 kpa

                       = 0.993 + 0.00141 atm

total pressure = 0.994 atm
