47.K V 100 ml 0.05n. М(NO3)2 (f´eq=1\2) added m g of cation exchanger in H-form. After equilibrium was established, the concentration decreased to C. Determine the static exchange capacity (mmol / g) of the cation exchanger, taking the molar mass of the equivalent M (1 / 2M2)
V, ml 50
M2 Cd
m,r=3
С, mol-eq/l = 0.006
