I need help understanding the steps involved in obtaining the empirical formula of a compound: 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 :-
As given, moles of barium (Ba) = 0.300 mol
moles of chlorine (Cl) = 0.600 mol
So, mole ratio of Ba:Cl = 0.300/0.6000
= 1: 2
So empirical formula of the compound = BaCl2
