Homework Help: Atmospheric pressure to gas pressure in the apparatus

  1. Nov 28, 2012 #1
    1. The problem statement, all variables and given/known data
    If the atmospheric pressure is 745 mm Hg, what is the gas pressure in the apparatus in atm?
    (Hint: the gas pressure is not equal to atmospheric pressure. Which is greater Pgas or Patm?)
    Be careful with your units, 10.2 cm is equal to 102 mm

    2. Relevant equations

    3. The attempt at a solution

    We don't know the apparatus, we don't know what you add to what, we don't know the units. There is no way we can help or comment on the problem itself.
