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 MTherefore, the molarity of CL- in solution is 0.8 M |
