# Will ice float in gasoline?

${\rho}_{\text{octane}}$ $=$ $0.75 \cdot g \cdot m {L}^{-} 1$; of course it should be less dense than water due to the well-known fact that it floats on water. And thus ice (${\rho}_{\text{ice}}$ $=$ $0.92 \cdot g \cdot m {L}^{-} 1$) would certainly sink in gasoline (or petroleum ether, the which we would use in the lab). If you ask your chemistry teacher nicely, he or she might allow you to demonstrate this practically. Hexanes and water can be easily separated after the experiment is over.
