Hydroxyapatite is the main mineral component of bone. How many grams of hydroxyapatite will dissolve in 1.00 L of H2O? Ksp = 2.34 × 10–59; Molar mass = 502.3 g/mol?

Question

Hydroxyapatite is the main mineral component of bone.  How many grams of hydroxyapatite will dissolve in 1.00 L of H2O? Ksp = 2.34 × 10–59; Molar mass = 502.3 g/mol?

I keep getting 5.83x10^-18 g but the answer is supposed to be 4.35x10^-5 g. I don't understand why

first set 2.34*10-59= (5x)^5*(3x)^3(1x)^1 which is from the balanced equation. you will get 84375(x)^9=2.34*10-59= 8.67*10-8 mol/liter then you take the 502 grams/ mol and the 1 liter and multiple them all together to get 4.35*10^-5
