Question

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.

Answer 1

At sTplstandsrd temberahae prestue) P 1atom Pressule Temberatune (T): 0 -27F3K V2 velume ime gas at sTP Kooo panRT R 0.0221(La nyk) 213 K 22.41 L

velume (v) 22. 41L = valume at sTp So, volume f Imele a af sTp 22.411 mass gas O.4812 mass s dan& ty f fas af STP v olesme of gas (at sTP) o.481 22.41L . at STP: 0.0215L Density
