1 egg mass = 60g and. 02 x 1023) comes from the number of atoms in 12 g of carbon-12 (this is the carbon isotope with six protons and six neutrons). Poster as pdf (or poster with white background as pdf). So, in the same way, 1 mole of carbon is 12 grams because it is 12 atomic mass units on the periodic table and 1 mole of iron is 56 grams because it is 56 atomic mass units on the periodic table. So, a Mole is just basically a convenient way to convert between grams and atomic mass units? So, if you have a sample with this number of lithium atoms, that sample is going to have a mass of 6. Well, we see it right over here. And then, that gives us this many atoms.
And then, if we wanna figure out how many moles, and it's going to be a small fraction of a mole because a mole is 72. It's just like dozen, but instead of twelve pieces, it means another "number of pieces". So, how do we go from the masses at an atomic scale to the masses, masses of samples that you see in an actual chemistry lab, or in, I guess you could say, r-scale of the world. Once we have gathered all the conversion information needed it becomes a matter of stringing the equation together and making sure our units cancel out to give us the units desired.

The kilogram is used for measuring, as you say, the mass of something and moles are used for measuring the amount of particles in something. This provides an easy way to express quantities especially when doing multi-step calculations during stoichiometry. We can use Avogadro's constant to calculate the number of atoms or molecules from the number of moles or vice versa, using the following relationship: Did you know…? What does amu stand for(11 votes). And so, just to review what we just did, we had milligrams of germanium. So, this is how many grams we have. The difference being that mass of a oxygen atom is more than that of a carbon atom.
