Could you explain to me what the molar mass is? I can't quite understand.
Thank you so much!

Thanks for your question. :)
Molar mass is the mass of one mole or 6.023 x 10 ^ 23 atoms of an element or a molecule. It is measured in grams per mole (g / mole) since it is the mass for one mole of substance.
If you are looking for the molar mass of a particular element, you can find it in the periodic table. It is the atomic mass shown under the element in the periodic table. For example, the molar mass of iron is 55.85 g / mol.
If you are looking for the molar mass of a molecule, you just need to add the molar masses of each of the atoms that make up the molecule to get the molar mass you are looking for. For example, for the molecule of CO2, you have to add the molar mass of a carbon to the molar mass of two oxygen to obtain the one of carbon dioxide. You should get 44.01 g / mol.
