An aqueous solution is prepared by dissolving 100 mg/L ofCaCl2 and 230 mg/L of Na2SO4 in water. Assuming that these salts dissociate completely,and that the dissociated ions do not undergo any additional reactions, calculate(a) the molar concentration of each ionic species;(b) the ionic strength of the solution;(c) the activity coefficient for each species (with the Davies equation);(d) the activity of each species
