What is the molar mass of fe?

Right, so Fe is the symbol for iron. The molar mass for iron is about 55.85 g/mol. You can find this number on the periodic table, it is the atomic mass. For molar mass, you just add the unit ‘grams per mole’ to it. Your teacher will want you to use this number for chemistry sums and things. It is a very important number for your calculations. Hope that is a help for you, mate. Cheers.

In periodic tables, you’ll often see Iron’s atomic mass written as 55.85 u (atomic mass units). That same value is used as the molar mass in grams per mole. It’s a standard value accepted in chemistry.

The chemical symbol Fe stands for Iron. Its molar mass (also called atomic mass) is approximately 55.845 grams per mole. This means one mole of iron atoms weighs about 55.845 grams.

If you’re doing calculations in chemistry, always use the rounded value given in your periodic table. Some tables list it as 55.85 g/mol, which is accurate enough for most purposes.

Note that this value is an average because iron has isotopes. The most abundant isotopes are Fe-54, Fe-56, Fe-57, and Fe-58. Their natural abundance is factored into the weighted average of 55.845 g/mol.

To put it simply, molar mass is the bridge between microscopic atoms and measurable quantities. For example, if you have 55.845 g of pure iron, you have exactly 6.022 × 10²³ atoms (one mole). That’s the beauty of Avogadro’s number combined with molar mass.
