# What is the atomic mass of calcium phosphate?

Well calcium metal has a mass of $40.08$ $g \cdot m o {l}^{-} 1$, and........
And phosphorus has a mass of $30.9737$ $g \cdot m o {l}^{-} 1$, And the oxygen ATOM has a mass $15.999$ $g \cdot m o {l}^{-} 1$,
So if I add these atomic masses up appropriately (with respect to $C {a}_{3} {\left(P {O}_{4}\right)}_{2}$), I get..............
