A mass of aluminium metal is heated in such a way that it was exposed to air. (1.751g Al) A compound containing aluminium and oxygen is formed. It has a mass of 3.311 g. What is the empirical formula of aluminum oxide according to this experimental data?
Added by Brad T.
Step 1
Calculate the mass of oxygen that combined with the aluminum: Mass of oxygen = Mass of aluminum oxide - Mass of aluminum Mass of oxygen = 3.311 g - 1.751 g = 1.560 g Show more…
