1. The problem statement, all variables and given/known data
Calculate the empirical formula of the compunds which have the following percentage compositions:
65.7% Sr, 10.4% Si, 23.9% O
3. The attempt at a solution
I know how to do it, I just wanna know that while converting grams of oxygen into moles, do I use 16 g as its molar mass or 32 g since it's a diatomic molecule?
