Group a used 5.00 moles of styrene and 0.0010 moles of benzoyl peroxide while group b used the same amount of benzoyl peroxide as group a but used only 1.50 moles styrene. what would the average molecular weight of each group's polymer sample be

Answer : Average molecular weight of group A = 104.0276 g

               Average molecular weight of group B = 104.0920 g

Solution :  Given,   Moles of group A styrene = 5 moles

                               Moles of group A benzoyl peroxide = 0.0010 moles

                               Moles of group B styrene = 1.5 moles

                               Moles of group B benzoyl peroxide = 0.0010 moles

              Molecular mass of styrene = 104 g/mole

              Molecular mass of benzoyl peroxide = 242.23 g/mol

Formula used :    Average molar mass = Total mass / Total moles

               For group A,

               Average molar mass of group A =

                                                                      =

                                                                       =

                                                                       =

                                                                       = 104.0276 g

   Average molar mass of group A = 104.0276 g

          For group B,

              Average molar mass of group B =

                                                                     =

                                                                     =

                                                                     =

                                                                     = 104.0920 g

    Average molar mass of group B = 104.0920 g

that's what i got you can count the number of atoms

it takes on an electronical energy
