10. Calculate the ionic strength of the solution obtained by mixing aqueous solutions of HCl, NaCl, BaCl2, the concentrations and volumes of which are given in the table.

Task: HCI (V=50 ml, C=1.5 mol/l); NaCl (V=5 ml, C=1.2 mol/l);
BaCl2 (V=20 ml; C=1.1 mol/l)
When calculating, remember that in the formula for calculating the ionic strength of a solution, you must know the concentrations of all ions in the prepared solution.
