Alright, so let's take a structure like this.
00:03
And you may or may not be familiar with this kind of rotting.
00:07
This is butanone.
00:09
And it has a formula c4, h8.
00:15
That means there are four carbons, eight hydrogens, and one oxygen.
00:19
And we want to investigate whether the element in the compound with the highest atomic mass always has the highest mass percentage.
00:30
So if we take c4h8 and we add up the mass of each individual atom in here, we'll have 4 times 12, which is 48, we have 8 times 1, which is 56, and then 0, which is 16.
00:52
So that'll be 72 in all.
00:55
So be it known as an atomic mass of 72 grams per mole.
01:05
Now let's look at the percent composition...
