Some ionic compounds contain a mixture of different chargedSome ionic compounds contain a mixture of different charged

cations. For example, some titanium oxides contain a mixture

of $T{i}^{2+}$ and $T{i}^{3+}$ ions. Consider a certain oxide of titanium that

is $28\mathrm{.}31\%$ oxygen by mass and contains a mixture of $T{i}^{2+}$ and

$T{i}^{3+}$ ions. Determine the formula of the compound and the

relative numbers of $T{i}^{2+}$ and $T{i}^{3+}$ ions.
