Question

An iron chloride compound contains 55.85 grams of iron and 106.5 grams of chlorine. What is the most likely empirical formula for this compound?

Answer 1

Answer:
Calculate number of moles:
Iron = 55.85 g/ 56 g/mole =1 mole
chlorine = 106.5 g/35.5 g/mole = 3 moles
The ratio is 1 to 3 therefore the simplest empirical formula is FeCl3
