139. Solving a chemistry problem

148. What mass of cobalt will remain in the solution if V (ml) of a CoSO4 solution with a concentration CHANCH was passed through a column filled with m (g) of a cation exchanger. The total dynamic capacity under separation conditions is 3.2 meq / g (equivalence factor - ½). Received the following data (in accordance with the task number) - table 45.
m, g 10.0
V, ml 500
First * mol / L 0.10
