This depends greatly upon the temperature the water. At 4oC the density is approximately 1000 kg/m3 (or 1 g/cm3) - more acurately though the density would be 999.97 kg/m3 (or 0.9997 g/cm3).

Values for the density of pure water (H2O) have been calculated over a wide range of temperatures. At room temperature (22oC) The density of water is 997.77 kg/m3 (or 0.99777 g/cm3).
