n.
The sum of the atomic weights of all the atoms in a molecule. Also called relative molecular mass.

molecular weight

n
(Chemistry) the former name for relative molecular mass

molec′ular weight′


n.
the average weight of a molecule of an element or compound measured in units based on 1/12 the weight of the carbon-12 atom; the sum of the atomic weights of all the atoms in a molecule. Abbr.: mol. wt.

molecular weight

The sum of the atomic weights of the atoms contained in a molecule. For example, since the atomic weight of hydrogen is 1 and the atomic weight of oxygen is 16, the molecular weight of water (H2O) is 1 + 1 + 16, or 18.
