Answer:
The molecular mass of a substance is the sum of atomic masses of all the atoms in a molecule of the substance. It is used for those substances whose constituent particles are molecules.
For example:
The moleculear mass of CO 2=(1× atomic mass of carbon) + (2 × atomic mass of oxygen)
⇒12+2×16
⇒12+32=44u
