Answer:
First of all lets calculate the total number of CL- ions.
=> One mol of HCL will give one mol of H+ and one mol of CL- when dissociates. Thus, .2 mol gives .2 mol CL-
=> One mol of Bacl2 will give one mole of ba2+ and 2 mol of CL- when dissociates. Hence, 0.1 mol will give .2 mole CL-
=> So the total mols of CL- are .2+.2 = .4
=> Molarity:
molarity M = Total moles of solute/ Volume of solution in liter.
= .4/.5 = 0.8 M
Therefore, the molarity of CL- in solution is 0.8 M
