Answer to Question #251114 in General Chemistry for Shems

Question

What is the partial pressure of each gas if the following amounts of substances are placed in a 25.0 L container at 25 °C? What is the total pressure of each mixture?

a. 1.570 mol of CH4 and 0.870 mol of COà ƒ ƒ ¢ ‚ ‚ b. 2.63 g of CO and 1.24 g of NO2

Answer 1

Consequently, the pressure of a gas in a mixture depends on only the percentage of particles in the mixture that are of that type, not their specific physical or chemical properties. By volume, Earth's atmosphere is about 78% N2, 21% O2, and 0.9% Ar, with trace amounts of gases such as CO2, H2O, and others.
