Favorite Answer. Calcium chromate CaCrO 4 7.1×10 –4. 0. What is the minimum volume of dripping water saturated with calcium carbonate that would be required to form a small stalactite that had a mass of 1.000 kg? Should I call the police on then? Phosphorus pentoxide, P2O5, containing a total of 4.91x10^22 atoms of phosphorus and oxygen. CaCO 3 (s)--> Ca 2+ (aq) CO 3 2-(aq) initial: solid. Calculate the molar solubility of this compound? Yahoo fait partie de Verizon Media. The equilibrium constant, Ksp, for aqueous solutions of ionic compounds at 25°C. I. To find the molar solubility we use the table They are calculated by using standard state thermodynamic data and the equations: ΔG° = m*ΔfG°(M+, aq) + n*ΔfG°(A-, aq) - ΔfG°(MmAn, s)        and       ln Ksp = -ΔG°/RT, Ksp is indicating the maximum concentration of the solved ionic substace in water at the actual (stable) temperature.
