Step 1

This tells us that for every one mole of $\mathrm{Fe}_{2} \mathrm{O}_{3}$, there are two moles of iron (Fe) atoms. This is because the subscript '2' in the formula indicates that there are two atoms of iron for every molecule of $\mathrm{Fe}_{2} Show more…

Key Concepts

Stoichiometric Coefficient

The stoichiometric coefficient is the numerical value found in a chemical formula that indicates the ratio of atoms of a particular element in a compound. This concept is essential for determining how many moles or atoms of one element are present in a mole of a compound based on its chemical formula.

Mole

The mole is a fundamental unit in chemistry that represents a specific number of particles, typically atoms or molecules. This number, known as Avogadro's number (approximately 6.022 x 10^23), is used to relate the macroscopic amount of a substance to the number of discrete entities it contains.

Avogadro's Number

Avogadro's number is the constant that defines the number of atoms, molecules, or other particles in one mole of a substance. It provides a bridge between the microscopic world of atoms and the macroscopic amounts we measure in the laboratory.
