Webmicro world. For example, we can represent five grams of iron in terms of the number of moles. We simply divide the five grams by the molar mass of iron. Molar mass is defined as the number of grams in one mole of a given element. Iron has a molar mass of 55.84 grams/mole. So, five grams divided by 55.84 grams/mole gives us 0.089 moles of iron. WebIron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, just ahead of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core.
