  3. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    The method is appealing to such users because sodium bicarbonate is widely sold as baking soda, and the temperatures required (250 °F (121 °C) to 300 °F (149 °C)) to convert baking soda to sodium carbonate are readily achieved in conventional kitchen ovens. [18]

  4. Sodium percarbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_percarbonate

    Sodium percarbonate or sodium carbonate peroxide is a chemical substance with empirical formula Na 2 H 3 C 2 O 6. It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na 2 CO 3 · 3 H 2 O 2. It is a colorless, crystalline, hygroscopic and ...

    en.wikipedia.org/wiki/Molar_mass

    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] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .

  8. Molecular mass - Wikipedia

    en.wikipedia.org/wiki/Molecular_mass

    In high-resolution mass spectrometry the mass isotopomers 12 C 1 H 4 and 13 C 1 H 4 are observed as distinct molecules, with molecular masses of approximately 16.031 Da and 17.035 Da, respectively. The intensity of the mass-spectrometry peaks is proportional to the isotopic abundances in the molecular species.
