Mole percent, or molar percent of a substance is the ratio of the moles of a substance in a mixture to the moles of the mixture. It represents the number of moles of a substance in a mixture as a percentage of the the total number of moles in the mixture. Mole % = (mol substance in a mixture) / (mol mixture) * 100

Iron is a pure substance. It's an element (Fe) and a bar of Iron is no mixture. If it was pure iron, then by definition it would be pure. However iron is rarely pure, it is usually in alloy with something.
Iron is an element. It is a pure substance that consists of only one type of atom, specifically iron atoms.
An iron sulfide is obtained: FeS2.
Yes, a new substance, iron sulfide, was formed after heating the iron-sulfur mixture. Iron sulfide is a chemical compound that results from the combination of iron and sulfur atoms during the heating process.
No, iron metal is not a solution. A solution is a homogenous mixture where one substance is dissolved in another. Iron metal is a pure substance composed of iron atoms.
Unheated sulfur and iron filings is a mixture. This is because the sulfur and iron filings retain their individual properties and can be physically separated.
No, iron is a pure substance because it is composed of only one type of atom. It is not a mixture because it does not contain multiple substances that are physically combined.
Iron sulfide is a pure compound. It can be as in aqueous medium too as a solution.
yes.
