Finding the molar mass of a single element is really simple. The unit used to measure is grams per mole.
Find the atomic mass for each element by using the mass given in the periodic table or table of atomic weights.
How to calculate molar mass. How to calculate molar mass the molar mass is the mass of one mole of a sample. The molar mass also known as molecular weight is the sum of the total mass in grams of all the atoms that make up a mole of a particular molecule. All you need to do is find the atomic mass of the element on the periodic table and report the number with the unit grams per mole or g mol.
To calculate the molar mass of an element find the relative atomic mass of that element then multiply the relative atomic mass by the molar mass constant. To calculate the molar mass of a compound calculate the molar mass of each element in the compound then multiply the element s atomic mass by the number of atoms of that element in the compound. From this you can see that sodium s molar mass will be 22 99 g mol.
To find the molar mass add the atomic masses atomic weights of all of the atoms in the molecule.
