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...

Item 26 Review l Constants i Periodic Table Learning Goal: To use partial pressure in gas law calculations In a mixture of gases, the total pressure of the gas mixture is equal to the sum of the partial pressures of the individual gases. For example, if you have a mixture of helium at 2 atm and argon at 4 atm, then the total pressure of the gas inside the cylinder is 6 atm . (Figure 1) Similarly, if you know...
