Answer:
E. None of the above.
Explanation:
Given 1 mole of iron. We need to find the mass of the iron. And we will compare mass of the iron with the given options.
The molar mass of the iron is 55.845 g/mol.
So, for 1 mole the mass of the iron would be [tex]55.845\times 1=55.845\ g[/tex]
Also, the molar mass of the lead is 207.2 g/mol.
So, for 1 mole the mass of the lead would be [tex]207.2\times 1=207.2\ g[/tex]
We can see that one mole of lead is heavier than one mole of iron. So, the only option is correct is E. None of the above.
The correct answer is none of the above.
• The given question is based on the molar mass of Fe or iron.
• 1 mole of iron (Fe) signifies that mass of 6.023 × 10²³ atoms of Fe is equivalent to 55.845 grams of iron.
• The mass of 1 mole of Pb or lead is 207.2 g/mol and the molar mass of Fe is 55.845 g/mol so Fe is not heavy than Pb.
• The mass of Fe is 55.845 g/mol so option B and C are also incorrect.
• The mass of 1 mole of Fe is not similar to mass of 1 mole of Pb.
Thus, based on the given options, option E, that is, none of the above is correct.
