35. Solving a chemistry problem

47.1 K V (ml) 0.05 N. M(N03)2 (feq=1/2) added m (g) cation exchanger in H - form. After equilibrium was established, the concentration decreased to c´. Determine the static exchange capacity (mmol/g) of the cation, taking the molar mass of the equivalent M (1/2M2):
V, ml Ме2 m, g с΄, mol/l
50 Cd 3 0.003
