Answer:

The answer to your question is: 63.5 u

Explanation:

Data                  Percent                         Molecular mass

63 Cu               69.2%                             62.9296 u

65Cu                 30.8%                             64.9278 u

Average atomic mass = ?

Formula

Average atomic mass = (0.692 x 62.9296) + (0.308 x 64.9278)

                                     = 43.55 + 19.99
