Steel can only withstand compressive loads, whereas cast iron is equally robust in compression and tension. If the mass of iron (Fe) is 454 g, (i) calculate the number of iron (Fe) atoms in one ton (2000 pounds), and (ii) calculate the volume in cubic centimetres filled by one mole of Fe. Given: NA = 6.022 x 1023 atoms/mol and Iron's atomic weight is 55.847 g/mol.

Answer:
(i) There are approximately 2.5 x 10^29 iron (Fe) atoms in one ton (2000 pounds).
(ii) One mole of iron (Fe) fills approximately 7.09 x 10^6 cubic centimeters.

Explanation:
(i) Calculate the number of moles of iron in one ton using its molar mass, then multiply by Avogadro's number to find the number of atoms.
(ii) Divide the molar mass of iron by its density to find the volume of one mole, then convert to cubic centimeters if needed.
