1. A gas mixture consists of 320. mg of methane, 175 mg of argon, and 255 mg of neon. The total pressure of the mixture is 28.3 atm. Calculate the partial pressure of each gas in the mixture. [ atm, atm, atm] 2. A quantity of N2 gas originally held at 466 kPa in a 1.00 dm3 (1 dm3 = 1 L) container at 26.0'C is transferred into a 10.0 dm3 container. A quantity of O2 gas originally held at 355 kPa in a 5.00 dm3 is transferred into the same container. What is the total pressure in the new mixture? [ kPa] 3. Methane reacts with oxygen to form CO2 and H20 as shown in the equation: CH4(9) + 202 - CO2(g) + 2H20(1) -- "sorry for the typo errors." If 15.0 moles of CH4 are reacted, what is the volume, in liters, of CO2 produced at 23.0 C and 0.985 atm? [ L]
