The element lead (Pb) consists of four naturally occurring isotopes with masses of 203.97302, 205.97444, 206.97587, n 207.97663
Zanzabum

Answer:

The atomic mass of lead is: 207.216 u

Explanation:

data                 Isotopes                     mass                      percent

                             1                      203.97302                      1.4

                             2                     205.974444                    24.1

                            3                      206.97587                       22.1

                            4                      207.97663                       52.4

atomic mass = (203.97302x 0.014) + (205.974444 x 0.241) +

                        (206.97587 x 0.221) + (207.97663 x 0.524)

atomic mass = 2.856 +49.639 + 45.742 + 108.979

atomic mass = 207.216 u
