The solubility of gold (V) oxalate, Au2(C2O4)5 is 2.58 g/L. Calculate Ksp from this information.
Answers: 2
![Ksp=[Au^{5+}]^2[(C_2O_4)^{2-}]^5](/tpl/images/0722/7385/d53dd.png)
![[Au_2(C_2O_4)_5]=2.58\frac{g}{L} *\frac{1mol}{834g} =3.09M](/tpl/images/0722/7385/0abfb.png)
![[Au^{5+}]=3.09x10^{-3}\frac{mol}{L} *\frac{2molAu^{5+}}{1mol} =6.19x10^{-3}M](/tpl/images/0722/7385/94888.png)
![[(C_2O_4)^{2-}]=3.09x10^{-3}\frac{mol}{L} *\frac{5mol(C_2O_4)^{2-}}{1mol} =0.0155M](/tpl/images/0722/7385/7e2fe.png)
