Question
6.) A manometer has one side attached to an apparatus containing a gas sample and the other side
exposed to an open atmosphere. The pressure of the gas sample was determined from the difference
in height of the liquid. If the liquid is mercury and the open side is 3.65 cm lower than the side
connected to the apparatus. What is the pressure (in atm) inside the apparatus given that the density
of mercury is 13.55 g/mL and the atmospheric pressure was 757 Torr.
A.) 0.996 atm
B.) 0.0478 atm
C.) 0.948 atm
D.) 1.04 atm
E.) 0.369 atm
