Answer is: <span>the predicted </span>density for calcium is 1.61 g/cm³.
d(Sr) = 2.63 g/cm³; density for strontium.
d(Ba) = 3.65 g/cm³; density for barium.
Ar(Sr) = 87.62 atomic weight for strontium.
Ar(Ba) = 137.33; atomic weight for barium.
Ar(Ca) = 40.08; atomic weight for calcium.
d(Ba) - d(Sr) = 3.65 g/cm³ - 2.63 g/cm³.
d(Ba) - d(Sr) = 1.02 g/cm³.
d(Ca) = d(Sr) - 1.02 g/cm³.
d(Ca) = 2.63 g/cm³ - 1.02 g/cm³.
d(Ca) = 1.61 g/cm³.
It belongs to one of two groups which orbit the sun at the same distance as Jupiter, at the Lagrangian points roughly 60 degrees ahead of it and behind it.
