Web28 dec. 2024 · The molar mass of a substance is the mass of one mole of the substance. This is based on Avogadro’s number, which tells you the number of atoms or molecules in one mole of a substance, and the definition of a mole. A mole is the amount of a substance that makes its mass in grams the same as its atomic mass number. 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. ccrn cammy
