A 2.27-L flexible flask at 15°C contains a mixture of N2, He, and Ne at partial pressures of 0.335 atm for N2, 0.199 atm for He, and 0.441 atm for Ne. (a) Calculate the total pressure of the mixture in atm. (b) Calculate the volume in liters at STP occupied by He and Ne if the N2 is removed selectively.
Question 7 3 pts A gas mixture that contains 322 g Ne and 21.6 g Oz has a volume of 43.0 L. At what temperature will the pressure of the gas sample be 1.65 atm? Assume the gas sample behaves ideally. Express your answer in units of degrees Celsius (C) using at least three significant figures.
A 137 mL flask contains 0.481 g of a gas at 767 torr and 22.0o C. b) What is the density of the gas at STP? Two other people have used a volume of 22.4 L when solving the problem (you can search/look this up). If someone could please explain where the 22.4 L is coming from, I'd appreciate it. I was under the impression the volume would be 0.137 L.
