Solvents

Solvent	Boiling Point °C	Solubility /w Water	Density	Molar mass
Acetone	56 °C	Miscible	0.786 g/ml	58.08 g/mol

Note about Density: If the density of the solvent is greater then one (mass > 1.00) the solvent, if non-polar will sink below water. likewise if the density is less then one (mass < 1.00) the solvent, if non-polar, will float on the surface of the water
