Solve the following question given below:
Question I: Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 6.3 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mole.
Question II: Imagine adding electrons to the pin until the negative charge has the very large value 1.10mC. How many electrons are added for every 10^9 electrons already present?
Please explain the equations and steps and numbers are used to get the answer. Thanks.
