The mass of 400 moles of Fe is approximately 55,800 grams.

**More detailed answer to your question**

According to the periodic table, the molar mass of Fe (iron) is approximately 55.845 grams per mole. Therefore, the mass of 400 moles of Fe can be calculated by multiplying the molar mass by the number of moles:

Mass of Fe = 55.845 g/mol × 400 mol = 22,338 g

In other words, the mass of 400 moles of Fe is approximately 22,338 grams or 22.338 kilograms.

As the famous physicist Albert Einstein once said, “Energy and mass are two sides of the same coin.” This statement highlights the fundamental relationship between mass and energy as described in Einstein’s famous equation, E=mc².

## Video answer to your question

This video provides a clear explanation of how to convert grams of iron to moles and then to atoms. The process involves dividing grams of iron by its atomic mass to obtain moles before multiplying the moles by Avogadro’s number to get the number of iron atoms. The video emphasizes the importance of dividing by the molar or atomic mass when converting grams to moles and multiplying by Avogadro’s number when converting moles to particles.
