Ksp is the equilibrium constant of solubility of a solid in a solution.
The solid is CaC2O4.
The dissolved ions are Ca2+ and C2O4 2-
The equation of the equilibrium is
Then Ksp = [Ca 2+][C2O4 2-]
Where the [ ] indicates molar concentration
The chemical equation for this equilibrium implies [Ca 2+] = [C2O4 2-]. Name X this quantity
Ksp = x^2 ==> x = square root of Ksp
x = sqrt(2.3 * 10^ -9) = 4.8 * 10^ -5
Which is the second option.

Answer:
The answer is in the picture.
Explanation:
The methanol molecule is on the top.
the three molecules are drawn in blue (the two water molecules and the methanol molecule), with the hydrogen bonds indicated with dashed lines. There are also oxygen lone pairs drawn as red dots, and the zones of negative density ( δ-, high concentration of electrons) and zones of positive density (δ+, low concentration of electrons) are marked.
