Parts per Million by Weight in Water The concentration of gas at ppm in water is usually expressed in pounds. To determine this concentration using metric units, how dense water needs to be established. The amount of water that is pure is, by definition, 1000.0000 kg/m 3. at a temperature of 3.98degC and the norm atmospheric pressure that was used from 1969. It was the norm to the kilogram. The kilo today can be defined as being equivalent to the mass that forms the basis of the kilogram. The water of the highest purity (VSMOW) in temperatures of 4 degrees Celsius (IPTS-68) and normal atmospheric pressure would have an average density of that range 999.9750 kg/m 3. . [5] The density of water can be affected by pressure, temperature and the presence of impurities i.e. dissolving gasses in addition to sodium salts in water. In addition, the high concentration of gaz that dissolve in water will impact the density of water. It is the nature of things that water is described b...
