  2. Methyl benzoate - Wikipedia

    en.wikipedia.org/wiki/Methyl_benzoate

    Methyl benzoate is an organic compound. It is an ester with the chemical formula C 6 H 5 COOCH 3, sometimes abbreviated as PhCO 2 Me, where Ph and Me are phenyl and methyl, respectively. Its structure is C 6 H 5 −C(=O)−O−CH 3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents.

  3. Molecular mass - Wikipedia

    en.wikipedia.org/wiki/Molecular_mass

    The derived quantity relative molecular mass is the unitless ratio of the mass of a molecule to the atomic mass constant (which is equal to one dalton). [2] The molecular mass and relative molecular mass are distinct from but related to the molar mass. The molar mass is defined as the mass of a given substance divided by the amount of the ...

  4. Methyl 4-iodobenzoate - Wikipedia

    en.wikipedia.org/wiki/Methyl_4-iodobenzoate

    Methyl 4-iodobenzoate, or methyl p-iodobenzoate, is an organic compound with the formula IC 6 H 4 COOCH 3. [3] It is the methyl ester of 4-iodobenzoic acid , or may also be viewed as an iodinated derivative of methyl benzoate .

  5. IUPAC polymer nomenclature - Wikipedia

    en.wikipedia.org/wiki/IUPAC_polymer_nomenclature

    A polymer is a substance composed of macromolecules. The latter usually have a range of molar masses (unit g mol −1), the distributions of which are indicated by dispersity (Đ). It is defined as the ratio of the mass-average molar mass (M m) to the number-average molar mass (M n) i.e. Đ = M m /M n. [4]

  6. 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 ...

  7. Molar mass constant - Wikipedia

    en.wikipedia.org/wiki/Molar_mass_constant

    The molar mass constant is important in writing dimensionally correct equations. [4] While one may informally say "the molar mass M of an element is the same as its atomic weight A", the atomic weight (relative atomic mass) A is a dimensionless quantity, whereas the molar mass M has the units of mass per mole. Formally, M is A times the molar ...
