Problem: 2.241 g of a sample of nickel reacts with oxygen to form 2.852 g of the metal oxide. Calculate the empirical formula of the oxide.

FREE Expert Solution

We're being asked to determine the empirical formula of nickel (metal) oxide.

Recall that according to the Law of Conservation of Mass, matter can neither be created nor destroyed, all that happens is that it changes forms. 

Therefore,

mass of nickel + mass of oxygen = mass metal oxide

Calculate the mass of oxygen:
