10Molecular weight is the sum of the atomic weights of all atoms in a molecule.
The molecular weight of water is 16 amu.
Water contains two hydrogen atoms and one oxygen atom.
The molecular weight of calcium carbonate is 100 amu.
Magnesium chloride contains only one chlorine atom.
Atomic weight of hydrogen is 1 amu.
To calculate molecular weight, we multiply atomic weight by the number of atoms present.
Molecular weight is expressed in kilograms.
In CaCO₃, oxygen atoms are three in number.
Comparing atomic structures helps us understand differences in electrons and shells.
