Answer:

1.052

Explanation:

In order to convert from grams of a substance to moles, we need to divide the given mass by the molar mass of the substance:

  • Moles = Mass / Molar Mass

All the required data is given by the problem:

  • Moles = 218.8 g / 207.90 g/mol = 1.052 moles

There are 1.052 moles in 218.8 grams of iron (III) sulfide.
