Alright, so you're given a balloon and the initial volume has 2 .46 liters and it has 0 .158 moles of gas in it.
00:17
If you add 0 .113 moles, assuming constant temperature and pressure, it asks what the final volume is.
00:35
So anytime you look at a question that's asking you for a final volume or a final amount of moles, given initial volume and moles and a constant temperature and pressure, that means that we're going to be using avogadro's law to solve that equation.
00:55
So we'll be using avogadro's law.
00:58
Avagadro's law states that initial volume over initial moles is equivalent to final volume over the final amount of moles.
01:07
So now we just need to plug in our equation to solve for our final amount of volume.
01:15
So what we'll do, we'll start plugging in.
01:19
So our initial volume is 2 .46 liters.
01:25
Our initial amount of moles is 0 .158...
