The density of pure water has to be by definition Till then this was mean definition for the kilogram. Today's the kilo is defined as being equal to the mass of the international prototype of the kilogram [4]. Even the concerning concentration of gas dissolved in the water is affecting the density of the solution.

By nature there's a chance that water contains a certain concentration of Deuterium which influences the density of the water. This concentration is also called the isotopic composition [6]. Accurate calculations on these conversions are only possible when the density of the water is measured. In practice the density of water is therefore set to 1. When calculating the conversion with this value you gets:.

PPM , or parts per million, is the number of parts of a substance in a million parts of the solution or mixture.

For example, let's assume you want to measure the salinity of water. PPM is the number of salt parts per a million parts of the entire solution, both water and salt. It states how many milligrams of the substance can be found in a liter of the solution or mixture.

Determine the PPM value for your solution. Let's say you have created a solution with PPM of oil. Parts per million. Solute density. From a salt of the metal : e. Make a ppm standard of Na using the salt NaCl. Hence, weigh out 2. From an acidic radical of the salt : e. Hence, weigh out 1. This means that
