Pb(NO3)2(aq)+2KCl(aq)→PbCl2(s)+2KNO3(aq)

Pb(NO3)2                                                                        KCl        

M1 = 2.05 M                                                                    M2 = 1.45M

V1 =                                                                               V2 = 40.5ml

n1 = 1 mole                                                                     n2 = 2

M1V1/n1         =       M2V2/n2

V1   = M2V2n1/n2M1

     = 1.45*40.5*1/2*2.05 = 14.32 ml

volume of Pb(NO3)2 solution is 14.32 ml
