The sum of the relative atomic masses of the constituent atoms of a molecule
Numerically, the same as the relative molecular mass of a molecule expressed in daltons.
The weight of any molecule which is the sum of the weights of its constituent atoms.
Molecular weight is the amount of mass of all the components of the molecule, which may include several atoms.
one of many polymer characteristics; the ratio of mass of a molecule to the unified atomic mass unit; abbreviated as Mw or Mn.
Molecular weight of a molecule is always calculated from the user-supplied atomic weights unless the natural abundance flag is set, in which case the atomic weights in the database are used.
The sum of the atomic masses of the elements forming the molecule. In high polymers the molecular weights vary so widely they must be expressed as averages.
molecular mass. Compare with formula weight and molecular formula. The average mass of a molecule, calculated by summing the atomic weights of atoms in the molecular formula. Note that the words mass and weight are often used interchangeably in chemistry.
The combined weight (as given on the periodic table) of all the elements in a compound.
The mass (in grams) per mole of a substance.
The total weight in grams of one mole of the molecule, i.e. 6 x 1023 molecules.
the relative weight of a molecule
The total obtained by adding together the weights of all the atoms present in a molecule. To Top
Molecular weight is the ratio of the average mass of one molecule of an element or compound to one twelfth of the mass of an atom of carbon-12.
The mass of one molecule of a nonionic substance in atomic mass units.
The molecular weight of a compound in grams is the sum of the atomic weights of the elements in the compound. The molecular weight of sulfuric acid (H2SO4) in grams is 98.
The sum of the atomic weights of all the atoms in a molecule. It is also the weight in atomic mass units of all the atoms in a given formula
The sum of the atomic weight of all of the atoms within a molecule. Generally, molecules of the same type have higher boiling points if the molecular weight is higher.
The sum of the individual atomic weights of the atoms which make up a molecule.
Sum of the atomic weights of all the atoms in a molecule. Sometimes referred to as mole weight or mol weight.
Is the sum of the atomic weights of the constituents, which make up a molecule.
The molecular weight of a substance is the sum of the atomic weights of the atoms present in its conventional formula.
The weight in grams of one mole of the chemical or compound.
The sum of the atomic weights of all the constituent atoms in the molecule.
The amount of mass in one mole of molecules of a substance as determined by summing the masses of the individual atoms which make up the molecule.
the mass of a single molecule of a given compound. In the case of large molecules, it is usually expressed in kiloDaltons ( kD). In the case of significantly smaller molecules, it is expressed in atomic mass units.
The sum of the atomic weghts of the atoms in a compound. The higher the molecular weight of a substance, the more viscous it is. Units are grams per mole.
the atomic weight of all atoms in a specific molecule.
The relative molecular mass of a molecule. Molecular weight is typically expressed in Daltons.
sum of the atomic weights of all elements in a molecule. It is measured in Atomic Mass Units (A.M.U.), commonly called Dalton (D).
Weight of the smallest quantity of a substance processing all its normal physical properties.
The formula weight of a compound, given by summing the atomic weights of atoms in the compound. Given in grams, the molecular weight is the weight of one mole of molecules in a compound.
The weight of 1 mole (equal to Avogadro's number of particles) of a particular molecule. The mass of 1 mole of carbon atoms is defined as 12 grams.
The weight of a molecule expressed on a scale in which the carbon isotope weighs exactly 12.0; represents the sum of the weights of all the atoms in a molecule. As air is a gas mixture, it does not have a true molecular weight, but an apparent molecular weight determined by the percentages of the molecular weights of each gas in a composition.
the mass in grams of one mole of a substance.
