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.
