Expert Solution

Initial                                                                      final

M1 = 4.5M                                                           M2 = 0.9M

V1 = 100ml                                                          V2 =

                M1V1     =    M2V2

                   V2      =     M1V1/M2

                            =   4.5*100/0.9    = 500ml >>>answer
