Explanation:
Calcium is the element of second group and forth period. The electronic configuration of Calcium is - 2, 8, 8, 2 or 
There are 2 valence electrons of Calcium.
Thus, calcium loses two electrons to sulfate ion and sulfate ion accepts these electrons to form ionic bond.
Calcium sulfate, 
is formed when 2 valence electrons of calcium are loosed and they are gained by sulfate ion.
Thus, the charge on the sulfate ion is -2.

<em><u>Density formula</u></em>
<em>d = m/V</em>
<em>d = 6.13g/1.5cm³</em>
<em>d = 4.08(6) g/cm³ ≈ 4.10 g/cm³</em>
