Completion of stoichiometric table

    Reagent                     FW (g/mol)        mass (g)         mmoles       Equiv.

Bromobenzene                 157.01              0.448             2.853          2.122

magnesium                      24.30               0.044             8.221          1.358

benzophenone                  182.22              0.245             1.344          1.000

diethyl ether                     74.12               2.810             37.86          28.161

theoretical yield                 = 1.344 x 10^-3 x 260.33 = 0.350 g

triphenylmethanol              260.33              0.350             1.344          1.000

melthing point of triphenylmethanol = 162 oC
