What is the total negative charge, in coulombs, of all the electrons in a small 1.20 g sphere of carbon? One mole of C is 12.0g, and each atom contains 6 protons and 6 electrons. Attempted to calculate the total number of electrons first and then using that to calculate the total negative charge. Came out with 8475.4, but MP says it is wrong.
