  2. Calcium carbonate - Wikipedia

    en.wikipedia.org/wiki/Calcium_carbonate

    Molar mass: 100.0869 g/mol ... it has been most frequently reported in women taking calcium supplements above the recommended range of 1.2 to 1.5 grams daily, for ...

  3. Carbonate hardness - Wikipedia

    en.wikipedia.org/wiki/Carbonate_hardness

    An aqueous solution containing 120 mg NaHCO 3 (baking soda) per litre of water will contain 1.4285 mmol/l of bicarbonate, since the molar mass of baking soda is 84.007 g/mol. This is equivalent in carbonate hardness to a solution containing 0.71423 mmol/L of (calcium) carbonate, or 71.485 mg/L of calcium carbonate (molar mass 100.09 g/mol).

  4. Calcium supplement - Wikipedia

    en.wikipedia.org/wiki/Calcium_supplement

    Persons consuming more than 10 grams/day of calcium carbonate (4 grams of elemental calcium) are at risk of developing milk-alkali syndrome, [19] but the condition has been reported in at least one person consuming only 2.5 grams/day of calcium carbonate (1 gram of elemental calcium), an amount usually considered moderate and safe. [20]

  5. Solubility table - Wikipedia

    en.wikipedia.org/wiki/Solubility_table

    Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.

  6. Grain per gallon - Wikipedia

    en.wikipedia.org/wiki/Grain_per_gallon

    Calcium and magnesium ions present as sulfates, chlorides, carbonates and bicarbonates cause water to be hard. Water chemists measure water impurities in parts per million (ppm).

  7. Orders of magnitude (mass) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(mass)

    However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes.

  8. Equivalent concentration - Wikipedia

    en.wikipedia.org/wiki/Equivalent_concentration

    Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.

  9. Aragonite - Wikipedia

    en.wikipedia.org/wiki/Aragonite

    Aragonite is a carbonate mineral and one of the three most common naturally occurring crystal forms of calcium carbonate (Ca CO 3), the others being calcite and vaterite.It is formed by biological and physical processes, including precipitation from marine and freshwater environments.
