An open-end manometer containing mercury is connected to a
container of gas, as depicted in Sample Exercise 10.2 in the
textbook. What is the pressure of the enclosed gas in torr in each
of the following situations?
1. The mercury in the arm attached to the gas is 15.6 cm higher
than in the one open to the atmosphere; atmospheric pressure is
0.985 at
2. The mercury in the arm attached to the gas is 13 mm lower
than in the one open to the atmosphere; atmospheric pressure is
0.96 atm . Express your answer using two significant figures.
