Okay, so for this first question, if four atoms of a have the same mass as six atoms of b, each a has a larger mass, right? because if there's few of them, they each need to have a larger molar mass.
00:24
So if a has the larger mass, we would say b has the smaller mass, smaller mass.
00:31
So the atoms of six atoms of c have less mass than three atoms of d.
00:50
Well, d must have the larger molar mass, okay, because there's fewer of them and they weigh more.
01:05
So that means if it has a larger molar mass, they must have fewer atoms per gram, because each one weighs more.
01:20
So the answer is going to be that c has more atoms.
01:27
Per gram.

Okay, so c, we've got six atoms of e, and they have a larger mass than six atoms of f...
