Hint:
Dissolution usually takes place between compounds that have similar polarities in their molecules. If we place a solid which is nonpolar into a nonpolar liquid, then "like dissolves like" implies that the solid will dissolve in the given liquid. However, the only forces that will cause the liquid to be attracted to the solid are weak London dispersion forces.

Due to the linear structure of the carbon dioxide molecule, the dipoles of the molecule cancel each other out and hence the $C{O_2}$ is nonpolar.
