Explanation:

CaCO3 = 1 atom of Ca(calcium) + 1 atom of C(carbon) + 3 atoms of O(oxygen)

molecular mass of CaCO3 is the sum of masses of its constituent atoms

Atomic mass of Ca is 40 u.

Atomic mass of C is 12 u.

Atomic mass of oxygen is 16 u.

Molecular mass of CaCo3

= mass of 1 atom of Ca + mass of 1 atom of C + mass of 3 atoms of O

= (40 + 12 + 3×16)u

= 100 u
