What is the empirical formula of a compound that is 50.7 percent antimony and 49.3 percent selenium by weight?

We assume 100 grams of the compound and turn those percentages into grams and get the moles.
50.7 grams antimony (1 mole Sb/121.8 gram)
= 0.41626 moles antimony
================================
Now, the smallest mole number (antimony) becomes 1 and the other number is divided by it(antimony) to get the empirical numbers.
0.62467 moles Se/0.41626 moles Sb
= 1.5
----------------so, this happens sometimes and this is what we do
(SbSe1.5)*2
= Sb2Se3
-----------------The empirical formula Antimony selenide
