The formula weight of a chemical compound is calculated by adding the atomic masses of each chemical element contained in the compound, while multiplying them by the number of atoms respectively.

From the periodic table, the atomic mass of each chemical element is:

Carbon = 12.0107 u

Nitrogen = 14.0067 u

Oxygen = 15.999 u

Formula weight of $Ca(NO_3)_2$ = $12.0107 + [14.0067+ (15.999 \times3)]\times 2$

$F = 12.0107 + [14.0067+ 47.997] \times 2\\\\F = 12.0107 + 124.0074$

F = 136.02 g/mol.
