Question

8. If you have a 3.0 L cylinder of compressed air that contains 2.0 g of O2, and 8.0 g of N2, then at
room temperature (assume 298 K), what would be the total pressure in the tank (in atm), and
the pressures of O2, and of N2 (also in atm) separately?

1. A guage on a compressed gas cylinder in a hospital reads 2.200 E3 psi (pounds per square inch).
(1.00 atm = 14.7 psi). Express this pressure in each of the following units:
a. atm
b. kPa
c. torr
d. mm Hg
