When you rub a gold sphere with rabbit's fur, the gold takes on a negative charge (and the rabbit fur positive). Suppose the gold sphere has a mass of 100.0 g and it obtains a net charge of 0.500 ?C. Estimate the number of electrons added to the gold sphere and the number of electrons originally there. (Hint: 1 mole contains an Avogadro's number of atoms = atomic weight in grams.) Scientific notation can be accepted: 1000 would be entered as 1e3, and 0.001 would be entered as 1e-3.
