When the salt dissolves, it dissociates as follows; AB --> A⁺ + B⁻ The molar solubility is amount of moles of the salt that can be dissolved in 1 L of solution. solubility of the salt is - 2.60 g/L, to find molar solubility we have to multiply by the molar mass. 2.60 g/L /241 g/mol = 0.0108 mol/L ksp = [A⁺][B⁻] molar solubility of salt is equal to the molar solubility of cation and anion ksp = (0.0108)(0.0108) ksp = 1.17 x 10⁻⁴
