2) Calculate the number of electrons contained in a small electrically neutral pin made of silver, with a mass of 15.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g / mol. (b) Suppose that electrons are added to the pin until the net negative charge equals 5.5 mC. How many electrons need to be added for every 109 electrons already present?
Determine how many electrons there are in total in your body and what is the total electrical charge of these electrons. Keep in mind that most of the atoms in your body have the same number of electrons, protons and neutrons. Consider the average composition of the human body of 75 kilograms mass as: 65% Oxygen, 19% Carbon, 10% Hydrogen, 3% Nitrogen, 2% Calcium and 1% Phosphorus. The atomic number of Oxygen is 8 and its atomic mass is 16...
