First of all, let's have a look what all is given in the problem.
00:04
Given is volume is given that is v1 equals to 450 ml, 450 ml, and initial moles of gas are given, that is 0 .084.
00:18
That means n1 is given as 0 .084 moles and the final volume is also given, that is 200ml.
00:27
What we are supposed to calculate, we have to calculate the, we need to calculate the end two.
00:40
That means we need to calculate the, how many moles of gas must you remove if the balloon is shrinked to 200 m.
00:49
That means we need to calculate the number of moles.
00:57
We need to calculate the number of moles that need to be removed.
01:06
That we are supposed to calculate.
01:10
So let's apply the formula v2 by v1 will be equal to n2 by n1 because from pv equals to nrt we can say that volume is directly proportional to n...
