Calculate the number of electrons in a small, electri-cally neutral silver pin that has a mass of 10.0 g. Silver has47 electrons per atom, and its molar mass is 107.87 g/mol.(b) Electrons are added to the pin until the net negativecharge is 1.00 mC. How many electrons are added forevery 109electrons already present?
