3. because you take the ratio and just use them as subscripts for its corresponding element. So if carbon came out to 2 and hydrogen came out to 6, then it would simply be C2H6.

5. Yes, no, yes.
The EMPIRICAL formula for a compound with the ratio of C2H6 is CH3. The empirical formula is the simplest formula that can be derived. The C2H6 COULD BE (but it isn't necessarily so) the molecular formula.
