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.
Quick Answer. The SI base unit for distance is the meter, according to the International System of Units. From this base unit, using a system of equations, a number of derived quantities are obtained, such as area, volume, speed and acceleration.
