The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The gram-atom is a former term for a mole of atoms, and gram-molecule for a mole of molecules. [ 7 ] Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass ( M r ). [ 8 ]
However, there is another cluster containing many metabolic substances like cholesterol and glucose at the limit with the blue part (g/L or mmol/L). [ citation needed ] The unit conversions of substance concentrations from the molar to the mass concentration scale above are made as follows:
Magnesium is a chemical element ... An adult body has 22–26 grams of magnesium, ... Serum levels are typically 0.7–1.0 mmol/L or 1.8–2.4 mEq/L. Serum magnesium ...

Magnesium absorption in the large intestine is mediated by the transporters TRPM6 and TRPM7. [25] The body contains about 25 grams of magnesium. [25] Of the body's magnesium, 50-60% is stored in bone, with the remainder, about 40-50%, being stored in muscle or soft tissue, with about 1% being in the plasma. [41]
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [2]
