Web9 de jun. de 1997 · He was the first to make a distinction between molecules of a substance and its atoms. From Avogadro's law, it follows that one molar volume of any gas contains the same number of molecules, 6.02252 × 10 23, now called Avogadro's number- … 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!
