As the anodes dissolve away, the cathodes on which the pure metal is deposited grow in size. The impurities in the copper anode include lead, zinc, nickel, arsenic, selenium, and several precious metal including gold and silver.
Hey there!:
Volume in mL:
3.5 * 1000 = 3500 mL
density = 1.2 g/mL
Therefore:
D = m / V
1.2 = m / 3.5
m = 1.2 * 3.5
m = 4.2 g
hope this helps!
