Calculate the mass of aluminum deposited on the purified aluminum metal by the application of a current of 1.225 kiloamperes for 30 minutes from a very large quantity of a solution containing Al3+ ion in the Al2O3/Na3AlF6 molten state. Assume that you're in the aluminum refining business and have thus constructed the appropriate electrochemical cell and have applied a potential suitable to reduce aluminum, but not high enough to cause any other reductions or oxidations from the molten mixture
A piece of galena has a volume of 5.4 cm3. If the density of galena is 7.5 g/cm3, what is the mass (in kg) of that piece of galena?
