A compound of iron and sulfur crystallizes in a lattice pattern described as cubic closest packed sulfide ions,with iron ions in all octahedral sites.What is its empirical formula?

Question

Quizplus · Accepted Answer

The compound is described as having a cubic closest packed sulfide ion lattice pattern, which means that the sulfide ions form a cubic lattice with the iron ions occupying all octahedral sites. This suggests that the empirical formula of the compound is FeS, as each iron ion would be surrounded by six sulfide ions in an octahedral arrangement. The other options include additional symbols (such as "U" and "B") that are not commonly used in chemical formulas and are not necessary for representing the empirical formula of this compound.
