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 SI unit of mass is the kilogram (kg). As mass is difficult to measure directly, usually balances or scales are used to measure the weight of an object, and the weight is used to calculate the object's mass. maria-vivanco | Student, Grade 11 | (Level 1) Valedictorian.
