What is Molecular mass?
The molecular mass of an element is defined as the sum of all the masses of the elements present inside the molecule. e.g. the molecular mass of water, in which there are two hydrogen atoms and one oxygen atom present, is 18 (i.e. 2 + 16). Also called its molecular weight.
Unit of Molecular Mass
SI unit of Molecular Mass or Molecular Weight is an atomic mass unit which in short is called a.m.u. It is sometimes represented by u which represents unified mass.
Molecular Mass
Molecular Mass is the mass of all the atoms present in a molecule. In ancient India and Greece, philosophers have first given the idea of atoms and deeply studied them. Around 500 BC.
Everything around is made up of very small units these units are atoms in the language of science, very small in the sense is in the range of 0.1 – 0.5 nanometers. These atoms join to form molecular which then join to form matter. For example, two atoms of hydrogen and one atom of oxygen joins to form one molecule of H2O which is water. Hence, the molecular mass in this case of H2O will be given as sum of mass of two atoms of hydrogen and one atom of oxygen.
