Equal molar amounts of neon were collected over water in two
identical 6.0-L flasks, one being at 30 degrees Celcius and the
other being at 20 degrees Celcius, respectively. The difference of
respective total pressures in two flasks was 845.8 torr. Use the
provided table of vapor pressure versus temperature (picture) to
calculate the number of moles of neon collected in each flask.

Station 2: Calculations with the Ideal Gas Law A Station Letter: A student reacted a strip of magnesium metal with 4.00 mL of 4.0 M hydrochloric acid and collected the hydrogen gas produced using the experimental setup you see at the station. Unfortunately, the student forgot to record the mass of the metal before they reacted it with acid. Determine the mass of the magnesium metal the student used in the experiment. For this experiment assume the pressure of the...
