  2. Table of specific heat capacities - Wikipedia

    en.wikipedia.org/wiki/Table_of_specific_heat...

    Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...

  3. Gas constant - Wikipedia

    en.wikipedia.org/wiki/Gas_constant

    γ 0 is the heat capacity ratio (⁠ 5 / 3 ⁠ for monatomic gases such as argon); T is the temperature, T TPW = 273.16 K by the definition of the kelvin at that time; A r (Ar) is the relative atomic mass of argon and M u = 10 −3 kg⋅mol −1 as defined at the time.

  4. Molar heat capacity - Wikipedia

    en.wikipedia.org/wiki/Molar_heat_capacity

    The ratio between the two, however, is the same heat capacity ratio obtained from the corresponding specific heat capacities. This property is most relevant in chemistry, when amounts of substances are often specified in moles rather than by mass or volume.

  5. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    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 ]

  6. Oxygen–argon ratio - Wikipedia

    en.wikipedia.org/wiki/Oxygen–argon_ratio

    In chemistry, a sample's oxygen–argon ratio (or oxygen/argon ratio) is a comparison between the concentrations of oxygen (O 2) and the noble gas argon (Ar), ...

  7. Gas composition - Wikipedia

    en.wikipedia.org/wiki/Gas_composition

    The Gas composition of any gas can be characterised by listing the pure substances it contains, and stating for each substance its proportion of the gas mixture's molecule count.Nitrogen N 2 78.084 Oxygen O 2 20.9476 Argon Ar 0.934 Carbon Dioxide CO 2 0.0314

  8. Argon - Wikipedia

    en.wikipedia.org/wiki/Argon

    Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. [10] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv).

  9. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    Mole ratio: Convert moles of Cu to moles of Ag produced; Mole to mass: Convert moles of Ag to grams of Ag produced; The complete balanced equation would be: Cu + 2 AgNO 3 → Cu(NO 3) 2 + 2 Ag. For the mass to mole step, the mass of copper (16.00 g) would be converted to moles of copper by dividing the mass of copper by its molar mass: 63.55 g/mol.
