The atomic weight of calcium is 40,078 +/- 0,004 (IUPAC, 2005).
Calcium's atomice weight is 40.078 amu (atomic mass units).
To calculate the formula weight of calcium fluoride (CaF2), you would add the atomic weights of calcium (Ca) and two atoms of fluorine (F). The atomic weight of calcium is 40.08 g/mol and the atomic weight of fluorine is 18.998 g/mol. Therefore, the formula weight of calcium fluoride is 40.08 + 2(18.998) = 78.076 g/mol.
