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...

Learning Goal: To apply the ideal gas law to problems involving
temperature, pressure, volume, and moles of a gas. The four
properties of gases (pressure P, volume V, temperature T, and moles
of gas n) are related by a single expression known as the ideal gas
law: PV=nRT The variable R is known as the universal gas constant
and has the value R=0.0821 L⋅atm/(mole⋅K). The units of R dictate
the units for all other quantities, so when using this value...
