Empirical formula?

Question

A compound is formed when 0.300 moles of barium combine with 0.600 moles of chlorine. What is the empirical formula for this compound?

Answer 1

Ba = 0.300 mol

Cl = 0.600 mol

Divide the mole amount of each element by the lowest # of moles to obtain the mole ratio of each element in the compound.

Ba = 0.300 / 0.300 = 1 mol Ba

Cl = 0.600 / 0.300 = 2 mol Cl

Empirical formula = BaCl₂
