General chemistry, organic, and biochemistry?
1. which is the largest and the smallest of these choices:
1mole hydrogen
1 molecule ethane
1 molecule methane
1 mole ethene
2. what is the next smallest of these choice above? why isn't it the smallest?
3. what is the next largest of these choice above? why isn't it the largest?
4.Rotate the C-C bond so that the molecule looks different. Does this change either the structural formula or chemical formula? if yes, which are changed and the way they are changed ?

1 mole of hydrogen is 6.02x10^23H. which is a very large number.
1 mole of ethane is 6.02x10^23 C2H6 which is even larger than H.
1 mole Ethane is your largest choice.
the molar mass of ethane(C2H6) is 30g
the molar mass of methane(CH4) is 16g
1molecule of methane is you smallest choice, because it 1) has less molecules, and 2) its mass is smaller.
1 molecule of ethane is your next smallest choice because it weighs more than methane but it's only 1 molecule vs the other choices which are 6.02x10^23 molecules/atoms.
At my tuition, we wouldn't have an introductory classification to each healthy chemistry and biochemistry. We only have biochem and organic chem, and out of the 2, the latter is the less difficult classification. So maybe the final natural Chemistry I category will likely be less difficult? Whether a category is handy or not also relies on the teacher you get, so ask any one at your college who's taken those classes earlier than and you can get a good notion of which one is extra priceless, simpler, more intriguing, etc.
