It depends on which hydroxide it is. Many metals have hydroxides.
The density of francium hydroxide was not estimated; an approximate estimation can be made by comparison with the alkali metals hydroxides.

http://www.jtbaker.com/msds/englishhtml/s4034.htm The specific gravity of Sodium Hydroxide (NaOH) is 2.13. The density of Water (H20) is 62.43 lbm·ft−3. So, the density of NaOH = 2.13 * 62.43 = 132.9759 lb/ft^3
The density of pure sodium hydroxide (solid) is 2,13 g/cm3.
Increasing the concentration of NaOH the density also increase.
The density of sodium hydroxide is 2,13 g/cm3.
The ammonium hydroxide solution 28 % has a density of 0,9 g/cm3 at 25 oC.

Deterium Hydroxide has the lowest density.
the molar mass of sodium hydroxide is 40g/mol mike

Depending how it is formed, the density varies from about 3 g/cm3 down to 2.6 g/cm3. Digby D. Macdonald, Penn State University.
Lithium floats one water because it is less dense (it has a density of 0.53 g/cm while water has a density of 1.0 g/cm3). On contact, however lithium an water react to form hydrogen gas and lithium hydroxide. The latter then dissolves in the remaining water.
