in seawater in terms of the conditional stability constants of metal complexes and the corresponding ligand concentration. Based on the conditional stability constants of organic Cu(II) complexes,
In the original version of the metric system the base units could be derived from a specified length (the metre) and the weight [mass] of a specified volume ( 1â7003100000000000000â 1000 of a cubic metre) of pure water.
The basic metric unit of mass is the kilogram (kg). Kilograms are the only basic unit to contain a metric prefix. For quantifying small masses, grams (g) or milligrams (mg) are used instead.Micrograms (Âµg) are used in microbiology and other laboratory work for extremely small masses.he basic metric unit of mass is the kilogram (kg).
