Titanium dioxide (TiO $_{2} ),$ the substance used as the pigment in white paint, is prepared industrially by reaction of $\mathrm{TiCl}_{4}$ with $\mathrm{O}_{2}$ at high temperature.
$\mathrm{TiCl}_{4}+\mathrm{O}_{2} \stackrel{\mathrm{Heat}}{\longrightarrow} \mathrm{TiO}_{2}+2 \mathrm{Cl}_{2}$
How many kilograms of $\mathrm{TiO}_{2}$ can be prepared from 5.60 $\mathrm{kg}$ of $\mathrm{TiCl}_{4} ?$
