Ignoring trace elements, a typical elemental composition (by mass) of the human body is as follows: 10.5 % H 66.3 % O 19.9 % C 3.3 % N Use these percentages, the molar mass values, Avogadro's number, and the atomic numbers to determine the total number of electrons (and protons) in a 73-kg human body (160 pounds). If these electrons and protons were placed 100 m apart (the distance of approximately one football field), then what would be the force of electrical attraction between them.

Question

Ignoring trace elements, a typical elemental composition (by mass) of the human body is as follows:

10.5 % H 66.3 % O 19.9 % C 3.3 % N
  1. Use these percentages, the molar mass values, Avogadro's number, and the atomic numbers to determine the total number of electrons (and protons) in a 73-kg human body (160 pounds).
  2. If these electrons and protons were placed 100 m apart (the distance of approximately one football field), then what would be the force of electrical attraction between them.
