What is the empirical formula of titanium white?
A common white pigment in pain, paper and plastics called titanium white is an oxide of the metal titanium, Ti. Analysis of titanium white shows that 26.37 g of a sample of the oxide contains 15.81 of metal.
What is the empirical formula of titanium white?
It will work out to be TiO2.
Weight of oxide = 26.37
Weight of metal = 15.81
Weight of oxygen = 10.56
Atomic weight of Ti = 47.9
Atomic weight of O = 16.0
Number of atom of Ti = 15.81 / 47.9 = 0.33
Number of oxygen atom = 10.56 / 16.0 = 0.66
Atom of Ti = 0.33 / 0.33 = 1
Atom of O = 0.66 / 0.33 = 2
So there are two oxygen atoms for every atom of Ti. The emperical formula will be TiO2.
