In this question, the substance represented by the diagram in a has been diluted to twice its volume.
00:09
So when you have something that is diluted, that means it becomes less concentrated.
00:19
And what we did was double the volume.
00:22
So if we increase the volume by a factor of two, we're going to decrease the volume to, excuse me, decrease the concentration by one half.
00:35
So we're looking for the box that has half the concentration.
00:40
And it appears that b is the right option.
00:44
It is indeed the correct option.
00:46
Notice that there are half as many solute molecules, green particles, as they are in a.
00:54
So b is the right answer...
