Hi there.
00:02
So in this given question, a balloon contains 0 .158 moles initially and the initial volume of a gas is 2 .46 liters.
00:14
And after addition of more gas, that is 0 .113 moles of gas, what will be the final volume of this balloon is we need to find out.
00:27
So let's move to our solution.
00:31
According to our gatherers law, okay? at constant temperature and pressure conditions, volume of a gas is directly proportional to the number of moles of the gas.
00:56
Means if volume increases, number of moles increases as well.
01:01
To remove this proportionality sign, what we do, we put a constant here.
01:08
Okay.
01:08
So, this means volume divided by number of most equals to a constant.
01:16
So from this we have a formula, v1 upon n1.
01:24
V1 divided by n1 is equals to v2 divided by n2 is equal to constant...
