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)
The element with 82 protons is lead (Pb). The number of electrons in a neutral atom of lead is equal to the number of protons, which is 82. To find the number of neutrons, you subtract the number of protons from the mass number, which is 125 neutrons for this isotope of lead.
To convert 8.016 to a fraction, we first need to consider the digits after the decimal point. Since there are three decimal places, we can express 8.016 as 8016/1000. To simplify this fraction, we can divide both the numerator and denominator by their greatest common factor, which is 8. Dividing both numbers by 8 gives us 1002/125. Therefore, 8.016 as a fraction in simplest form is 1002/125.
82/125
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
The mixed number for 8.016 is 82/125
It is 77.33 recurring.
