Sorry, the video was turned 90 degrees from vertical.
The logic of PV = nRT is used to find the density of a gas. Given STP and the molar mass, we use the fact that at STP 22.4 L of a gas = 1 mol of that gas. Given the molar mass you have to find the density. The problem is completely worked out. This video should have ended at 6 min, I started #49 but that was a bad solution, so do not follow that one. See my other video on questions 49.
