This is a very high concentration and in the body we use the milliosmole (i.e. one thousandth of an osmole). â¢ Osmolality is the number of osmoles of solute particles per unit weight of solvent and has units osmoles/kilogram. Again in the body we use milliosmoles.
Perrier, also from France, is quite low in sodium and has a moderate amount of calcium, but it doesnât provide a whole lot of magnesium. Hereâs a chart that shows the amount of various minerals in several common brands of mineral water.

However, there are some industrial applications where hard water may lead to inefficiencies or damage to containers and pipes.
