We want to find how much charge is on the electrons in a nickel coin. Follow this method. A nickel coin has a mass of about 4 g. Each mole (6.02 × 1023 atoms) has a mass of about 58 g

Answer 1

4 grams of Ni (1mole/ 58 g of Ni)(6.02 x 10²³ atoms/mole)(28 electrons/mole Ni)(1.602 x 10^-19 coulombs/electron) = coulombs
