If the pressure of the gas inside the flask were increased and the height of the column in the open-ended arm went up by 0.5mm, what would be the new pressure of the gas in the flask, in torr?
ANSWER IS 807.3 TORR

  2. This question [is a sample problem in Section 10.2 of the Beer, et. al. Chemistry text book and] is a follow up to the one asked and answered here:

    Initial conditions needed to solve this question:
    P_atmo = 764.7 torr
    h_atmo = 136.4 mm (of Hg)
    h_gas = 103.8 mm (of Hg)

    Calculate the new heights:
    h_atmo2 = h_atmo + 5.0 mm = 141.4 mm
    h_gas2 = h_gas - 5.0 mm = 98.8 mm

    Then plug and chug:
    P_gas2 = P_atmo + (h_atmo2 - h_gas2)
    = 764.7 + (141.4 - 98.8)
    = 807.3 torr
