Section 5: Challenge Problem
1. A mixture of two ideal gases has the following conditions: Gas A has a pressure of 1.0 atm, a volume of 5.0 L, and contains 1.0 mole. Gas B has a pressure of 2.0 atm, a volume of 3.0 L, and contains 0.5 moles. Calculate the total pressure exerted by the gas mixture if the two gases are combined into a single container of 8.0 L at the same temperature.
