a) Calculate the electrical force between a gram of protons and the same number of electrons that are separated by 1 m. (There are about 5.979x1023 protons in a gram, each with a charge of +1.602x10-19 C; charge on an electron is the same magnitude but negative
(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) Imagine adding electrons to the pin until the negative charge has the very large value 3.00 mC. How many electrons are added for every 109 electrons already present?
