C2D3 has a solubility product constant of 9.14×10−99.14×10−9. What is the molar solubility of C2D3?
Express your answer with the appropriate units.
Molar solubility= 6.89 *10^-39. What are the units?

At equilibrium:
C2D3 <----> 2 C3+ + 3 D2-
2s 3s
Ksp = [C3+]^2[D2-]^3
9.14*10^-9=(2s)^2*(3s)^3
9.14*10^-9= 108(s)^5
s = 9.672*10^-3 M
Answer: 9.67*10^-3 M
