103.5 is the average.
82% of 125 = 82% * 125 = 0.82 * 125 = 102.5
82/125 = .656 Answer is 65.6%
43 + 82 = 125
The mixed number for 8.016 is 82/125
The answer to this is 13. 125-43=82+ 13=95
82% of 125 = 82% * 125 = 0.82 * 125 = 102.5
82/125 = .656 Answer is 65.6%
43 + 82 = 125

Lead is an atom consisting of 82 protons and 82 electrons. The number of neutrons depends on the isotope of lead. Pb-207 isotope has 125 neutrons (207 - 82 = 125)
82 electrons 82 protons 125 neutrons
8.016 = 8016/1000 = 1002/125 or 82/125
82/125
Pb (lead) 82 protons 82electrons 125 neutrons
Look on the periodic table for the element with the closest atomic mass to that number. It's lead (Pb, #82.) Now, for the neutron count, you round that atomic mass to the nearest whole number, which is 207, then subtract the atomic number of 82 from it. 207-82=125. So 125 neutrons.
Lead has: 82 Protons 82 Neutrons 125 Electrons
8.016 = 816/1000 = 82/125
