Question 117

Two oxides of titanium, A and B, were analysed.

The empirical formula of oxide A was found to be TiO2\text{TiO}_2TiO2​.

The results of the analysis of oxide B showed it contained 1.44 g of titanium combined with 0.72 g of oxygen.

Show, by calculation, that the two oxides have different empirical formulae.

(Relative atomic masses: O=16.0\text{O} = 16.0O=16.0, Ti=48.0\text{Ti} = 48.0Ti=48.0)
