2. Template:Chem molar mass - Wikipedia

   en.wikipedia.org/wiki/Template:Chem_molar_mass

   This template calculates the molecular mass (or molar mass) of a chemical compound. It is designed to be embedded in infoboxes {{ Infobox drug }} and {{ Chembox }} , but it can be used in-line just as well.

3. Molar mass - Wikipedia

   en.wikipedia.org/wiki/Molar_mass

   In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.

4. Thermodynamic databases for pure substances - Wikipedia

   Row 1. Molar mass of species, density at 298.15 K, ΔH° form 298.15, S° 298.15. and the upper temperature limit for the file. Row 2. Number of C p equations required. Here, three because of three species phases. Row 3. Values of the five parameters for the first C p equation; temperature limit for the equation. Row 4.

5. Molecular mass - Wikipedia

   en.wikipedia.org/wiki/Molecular_mass

   The molar mass is defined as the mass of a given substance divided by the amount of the substance, and is expressed in grams per mol (g/mol). That makes the molar mass an average of many particles or molecules (potentially containing different isotopes), and the molecular mass the mass of one specific particle or molecule. The molar mass is ...

6. Ebullioscopic constant - Wikipedia

   en.wikipedia.org/wiki/Ebullioscopic_constant

   M is the molar mass of the solvent. T b is boiling point of the pure solvent in kelvin. ΔH vap is the molar enthalpy of vaporization of the solvent. Through the procedure called ebullioscopy, a known constant can be used to calculate an unknown molar mass. The term ebullioscopy means "boiling measurement" in Latin.

7. Molar mass distribution - Wikipedia

   en.wikipedia.org/wiki/Molar_mass_distribution

   The number average molar mass is a way of determining the molecular mass of a polymer.Polymer molecules, even ones of the same type, come in different sizes (chain lengths, for linear polymers), so the average molecular mass will depend on the method of averaging.

8. Absolute molar mass - Wikipedia

   en.wikipedia.org/wiki/Absolute_molar_mass

   The next step is to convert the time at which the samples eluted into a measurement of molar mass. This is possible because if the molar mass of a standard were known, the time at which this standard eluted should be equal to a specific molar mass. Using multiple standards, a calibration curve of time versus molar mass can be developed. This is ...

9. Amount of substance - Wikipedia

   en.wikipedia.org/wiki/Amount_of_substance

   Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...
