One mole of a substance is equal to a very large number, 6.023 x 10 23 of atoms (or molecules) which the substance is made of. Molar mass is the relationship between the mass of a substance and the number of particles that make it up.It is expressed in kilograms per mole, but it is more common to see it presented in grams per mole (g/mol). The number of things in a mole is large, very large (6.0221415 x 10 23).We are all familiar with common copy-machine paper that comes in 500 sheet reams. The characteristic molar mass of an element is simply the atomic mass in g/mol. ‎CMM! However, because we want to cancel the gram unit and introduce moles, we need to take the reciprocal of this quantity, or 1 mol/18.015 g: n. The sum of the atomic weights of all the atoms in a molecule. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … Cobalt = 59g Bromine = 80g 1 mole elementIron = 56 g Calcium = 40 g 7.
