(a)
Interpretation:
The weight and cost of Pt and Fe needs to be determined.
Concept Introduction:
Platinum is a precious metal which is also very expensive. These materials are corrosion resistant and are very good conductors of electricity. As a result, the alloys of these metals are often used for electrodes of devices. These electrodes are formed using thin film deposition or screen printing of metal powder dispersions. The substance that gives away the electrodes is said to be oxidized. Platinum is used in automobile catalytic converter for the process of oxidation.
(b)
Interpretation:
The difference in the cost and weight of Pt and Fe needs to be determined.
