isotopes of masses : m1= 70.95 amu

                                 m2 = 72.95 amu

abundances :       A1 = 30.9 % = 0.309

                             A2 = 69.1% = 0.691

average atomic mass = ( atomic mass of isotope 1 x abundance 1 + atomic mass of isotope 2 x abundance 2 )

                                    = (70.95 x 0.309 + 72.95 x 0.691)

                                    = 72.33 amu

average atomic mass    = 72.33 amu
