Rank the following five salts in order of decreasing solubility, in terms of mass per unit volume.
(The most soluble gets rank 1, the least soluble gets rank 5.)

Hg₂CO₃     (K_sp = 9.00×10^-15; Note: The cation is Hg₂²⁺)
Hg₂Cl₂     (K_sp = 1.10×10^-18; Note: The cation is Hg₂²⁺)
Ca₃(PO₄)₂     (K_sp = 1.30×10^-32)
Ag₃PO₄     (K_sp = 1.80×10^-18)
Ca₅(PO₄)₃OH     (K_sp = 6.80×10^-37)

This is the 2nd time I've posted this question because previously people just listed it in order of the KSP that's given in the question. That is INCORRECT. I need to convert it to mass/volume. I've tried it 4 times and I keep getting the answer wrong.

Expert Solution

1 ) solubility of Hg2CO3 = Ksp^1/2 = (9*10^(-15))^(1/2) = 9.5*10^-8

solubility im mass/volume = 9.5*10^-8*molarmass of Hg2CO3

Molar mass of Hg2CO3 is 461.1889 g/mol

solubility im mass/volume = 9.5*10^-8*461.1889 = 4.38*10^-5 g/L

2) solubility of Hg2Cl2 = (Ksp^1/4)^(1/3) = ((1.1*10^(-18))/4)^(1/3)

= 6.5*10^-7

solubility im mass/volume = 6.5*10^-7*molarmass of Hg2Cl2

Molar mass of Hg2CL2 is 472.09 g/mol

solubility im mass/volume = 6.5*10^-7*472.09

= 0.0003068585 = 3.07*10^-4 g/L

3)

solubility of Ca3(PO4)2 = (Ksp^1/108)^(1/5) = ((1.3*10^(-32))/108)^(1/5)

= 1.64*10^-7

solubility im mass/volume = 1.64*10^-7 *molarmass of Ca3(PO4)2

Molar mass of Ca3(PO4)2 is 310.1767 g/mol

solubility im mass/volume = 1.64*10^-7 *310.1767

= 0.0003068585 = 5.1*10^-5 g/L

4)

solubility of Ag3PO4 = (Ksp^1/27)^(1/4) = ((1.8*10^(-18))/27)^(1/4)

= 1.6*10^-5

solubility im mass/volume = 1.6*10^-5 *molarmass of Ag3PO4

Molar mass of Ag3PO4 is 418.5760 g/mol

solubility im mass/volume = 1.64*10^-7 * 418.5760

= 0.0003068585 = 6.9*10^-5 g/L

5)

solubility of Ca5(PO4)3OH = (Ksp^1/84375)^(1/9) = ((6.8*10^(-37))/84375)^(1/9)

= 2.72*10^-5

solubility im mass/volume = 2.72*10^-5 *molarmass of Ca3(PO4)2

Molar mass of Ca5(PO4)3OH is 502.3114 g/mol

solubility im mass/volume = 2.72*10^-5 *502.3114

= 0.0003068585 = 0.014 g/L

ORDER OF SOLUBILITY

Ca5(PO4)3OH > Hg2Cl2 > Ag3PO4 > Ca3(PO4)2 > Hg2CO3
