The molar solubility of CaSO4 in water is 0 .67 gram per liter of solution. Calculate the Ksp.

2.4 * 10^-5

Explanation:

Molar solubility of CaSO4  = 0 .67 g/L/136 g/mol = 4.9 * 10^-3 Mol/L

Given that;

CaSO4(s) > Ca^2+(aq) + SO4^2-(aq)

Hence, Ksp = [Ca^2+] [SO4^2-]

Where  [Ca^2+] =[SO4^2-]=s

Ksp = s^2

since s = 4.9 * 10^-3 Mol/L

Ksp = (4.9 * 10^-3 Mol/L)^2

Ksp = 2.4 * 10^-5
