### HW 1 Problem F.9

When asked, "what atom ratios are the atoms present", does it mean find the empirical formula?

Yes, they are asking for the empirical formula.

I believe they are asking you to find the empirical formula after you find the mole ratio of the compound.

Yes, the ratio of the atoms would be the empirical formula.

### Re: HW 1 Problem F.9

yeah I was confused too but I guess since avogradro is a constant the ratios for the moles are the same as the ratios for the atoms since they're all being multiplied by the same thing.

The answer provided in the textbook is the empirical formula. Though I assume since it wasn't specified, any sort of ratio would suffice. I just included both the decimal values I got from my calculations, as well as the empirical formula.

Yes, the empirical formula is the ratio of elements, unlike the molecular formula which gives you the exact numbers of elements in a compound.
