The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's valence. That is, in grams, the atomic weight of the element divided by the usual valence. [2]
An adult body has 22–26 grams of magnesium, [15] [112] with 60% in the skeleton, 39% intracellular (20% in skeletal muscle), and 1% extracellular. [15] Serum levels are typically 0.7–1.0 mmol/L or 1.8–2.4 mEq /L. Serum magnesium levels may be normal even when intracellular magnesium is deficient.

Magnesium is important to the health of your bones, heart and brain. It's great to get it via food, but here's the best time to take magnesium supplements.
The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...
Normal magnesium levels are between 0.6 and 1.1 mmol/L (1.46–2.68 mg/dL) with levels less than 0.6 mmol/L (1.46 mg/dL) defining hypomagnesemia. [1] Specific electrocardiogram (ECG) changes may be seen. [1] Treatment is with magnesium either by mouth or intravenously. [2] For those with severe symptoms, intravenous magnesium sulfate may be ...
