2. Chapter 9 Worked Example 2
A student attaches a glass bulb containing neon gas to an open-tube
manometer and calculates the pressure of the gas to be atm.
If the atmospheric pressure is 762 Torr, what height difference
between the two sides of the mercury in the manometer did the
student find?
(b) Which side is higher, the side of the manometer
attached to the bulb or the side open to the
atmosphere?
(c) If the student mistakenly switches the numbers
for the sides of the manometer when recording
the data in the laboratory notebook, what
would be the reported pressure in the gas bulb?

A sample of methane gas, CH4, was slowly heated at a constant pressure
of 0.90 bar. The volume of the gas was measured at a series of different
temperatures and a plot of volume vs. temperature was constructed.
The slope of the line was 2.88×10-4 L K-1. What was the mass of the
sample of methane?
