However, one gram of hydrogen reacts with 8 grams of oxygen to give water or with 35.5 grams of chlorine to give hydrogen chloride: hence 8 grams of oxygen and 35.5 grams of chlorine can be taken to be equivalent to one gram of hydrogen for the measurement of equivalent weights. This system can be extended further through different acids and bases.
One liter of Ringer's lactate solution contains: [13] 130–131 mEq of sodium ion = 130 mmol L −1; 109–111 mEq of chloride ion = 109 mmol L −1; 28–29 mEq of lactate ion = 28 mmol L −1; 4–5 mEq of potassium ion = 4 mmol L −1; 2–3 mEq of calcium ion = 1.5 mmol L −1; Ringer's lactate has an osmolarity of 273 mOsm L −1 [14] and ...
An adult body has 22–26 grams of magnesium, [15] [113] 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
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 ...
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 any ...
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]

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]
