Do you always go from empirical to molecular? Could you go from molecular to empirical and is that something that occurs? Also if that is a thing, why would from molecular to empirical?

Re: Clarification
You can find the empirical formula from the molecular by simplifying the ratio. For example, IF the molecular formula was Os3C12O12, the ratio 3:12:12 can be simplified to 1:4:4, so the empirical formula would be OsC4O4

Re: Clarification
I'm sure you can go from molecular back to empirical but I'm not sure if you'll ever have to do it. If you do you would need all of the factors including obviously the actual compound that you're converting, the ratio, the molecular mass when it's at its highest and the molecular mass of the compound it self so you could work backwards.

Re: Clarification
It is possible to go from molecular to empirical. You would just need to get each of the subscripts in the formula and change it so they are at the simplest ratio and still keeping whole numbers. I don't think we would really need to do this though.

Re: Clarification
I'm fairly certain that you can find both if we are given enough information. It's just like how we can find the mass of sample, the number of moles, and the molar mass of the element if we are given at least 2 of these.

I think you meant to say that the coefficients in the chemical equation need to be at its simplest ratio to go from the molecular to empirical formula. You are not supposed to change the subscripts in a chemical equation because they indicate the number of atoms of an element present in chemical formulas.
