) Avogadro's Number calculations You carry out an experiment using a procedure similar to that described for lab 2, except that the metal you use is aluminum, which will form A3tions when dissolved. The power supply you use provides a current of 1.20 amperes. The aluminum originally weighs 12.486 g. After y passed current through the circuit for 5 minutes 50 seconds, the aluminum weighs 12.428g (Information which may or may not be useful: charge on an electron: 1.602 10-19...
2. If water has 10 electrons per atom (1 from each hydrogen, 8 from the oxygen), there are 18 g of water per mole and Avogadro's number (6.022 x 1023) of atoms per mole, how many grams of water do you need to have one Coulomb of charge from electrons?
