Densities of the alcohols

It is essential that chemists remember the density of water - it is exactly 1 g cm^-3. Using this information you should be able to decide whether the following alcohols will sink or float (of course, they may dissolve!):

Alcohol	density (g cm^-3)	Alcohol	density (g cm^-3)
Methanol	0.793	Ethanol	0.789
Propan-1-ol	0.804	Butan-1-ol	0.810
Pentan-1-ol	0.815	Hexan-1-ol	0.820
Heptan-1-ol	0.822	Octan-1-ol	0.826
