Set up your Chem 105 lab kit tub and fill it up. Be sure to let it sit overnight
so the temperature stabilizes to room temperature. Tap water can go in
this tub.

Calculate the atmospheric pressure of your environment in
mmHg from a weather barometric reading.
Calculate the pressure exerted by the collected O2 at the
water temperature. Ptotal=Po₂+PH₂o and the vapor pressure of
H₂O at 24 °C = 22.4 mm Hg)
Convert this pressure to atmospheres OR kPa.
