Expert Solution

Before dilution                                                 After dilution

M1   = 0.0015M                                                M2 = 0.000051M

V1    =                                                               V2    = 50ml

M1V1    = M2V2

    V1   = M2V2/M1

           = 0.000051*50/0.0015   = 1.7ml >>>>>>answer
