# What is the mass of 1 mole of iron?

Contents

The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.

## How do you find the mass of one mole of iron?

1. The mass of one mole of any element is given by its molar mass. Iron has a molar mass of 55.845 g mol−1 , which means that every mole of iron has mass of 55.845 g . Now, one mole of any element is defined as 6.022⋅1023 atoms of that element — this is known as Avogadro’s number.
