How did avogadro's number come about
WebNumber of moles of Ag = 0.201/108 = 0.00186. That means that there must have been 0.00186 moles of electrons in that 180 coulombs we have already calculated. We can find out how many coulombs there are in 1 mole of electrons by dividing 180 by 0.00186. Note: If your maths isn't very good, you might not like this! WebWhat is the Avogadro constant?
