Question

A compound has 85 % tin and 15% antimony. How many grams of antimony will be in 50. grams of the compound. My question is do I need to calculate the empirical formula first to do thi? I'm not sure where to start.

Answer 1

No. Tin and antimony are elements. Therefore their formulas (Tin- Sn | Antimony - Sb) are already in the simplest proportion formula wise. So that's the Empirical formula.

That's where you start and answers do you need the Empirical formula

Answer 2

I don't know that I buy the argument that SnSb is the empirical formula but I agree you don't need it.
