m/z value is nothing but molar mass value for M+ (Molecular ion)
ion for any compound.
Calculate Molar mass of any compound from the summation of all
individual atomic massess
For example
bromobenzene (C6H4NO2Br) = [(6 x C) + (4 x H) + (1 x N) + (2 x
O) + (1 x Br)]
                                         Â
= [(6 x 12.0107) + (4 x 1.00794) + (1 x 14.0067) + (2 x 15.9994) +
(1 x 79.904)]
                                         Â
= 202.0055 g/mol
