Okay, so for this question, they're asking whether the empirical and the molecular formula have the same percent composition of an element.
00:09
So the best way to show you guys how to do this is just give an example.
00:15
So let's say we have c4h602.
00:20
This is the molecular formula.
00:22
And the empirical formula of c4h602 would be c2 h3o.
00:27
So carbon is 12 grams.
00:33
We have four of them.
00:35
This will equal 48 grams.
00:37
Hydrogen is one gram.
00:39
We have six.
00:40
This will give us six grams.
00:42
And then oxygen is 16 grams.
00:45
We have two of them.
00:46
This will give us 32.
00:48
If we add it all together, we would get 48 plus 32 plus 6...
