There are four isotopes of lead and their relative abundance listed below.  use this information to calculate the approximate atomic mass of lead.  show all work   (4 points)                     82 protons, 122 neutrons, 1.4%                     82 protons, 125 neutrons, 22.1%                   82 protons, 124 neutrons, 24.1%                 82 protons, 126 neutrons, 52.4% show !

The approximate atomic mass of lead is 207.24 amu.

Explanation:

Abundance of isotope (I) = 1.4% = 0.014

Atomic mass of the Isotope (I) = number protons +  number of neutrons = 82 + 122 = 204 amu

Abundance of isotope (II) = 22.1 % = 0.221

Atomic mass of the Isotope (II) = number protons +  number of neutrons = 82 + 125 = 207 amu

Abundance of isotope (III) = 24.1% = 0.241

Atomic mass of the Isotope (III) = number protons +  number of neutrons = 82 + 124 = 206 amu

Abundance of isotope (IV) = 52.4% = 0.524

Atomic mass of the Isotope (IV) = number protons +  number of neutrons = 82 + 126 = 208 amu

Average atomic mass of an element =

Average atomic mass of lead =

The approximate atomic mass of lead is 207.24 amu.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
