How many protons are in an atom of an element? How many neutrons? How many electrons? Use this game to practice the calculations! Counting Atoms (Lab). Balancing Chemical Equations (Video).The mole enables us to count atoms in the laboratory. The mole is useful whether or not we know how many atoms of carbon-12 there are in 12.000 g of carbon-12. If we weigh one mole of iron and one mole of sulfur, we know that these two samples contain the same number of atoms. This is the important aspect of the mole. How many atoms there are in a mole is of subsidiary importance. Nonetheless, it has become possible to determine this number.

The accuracy of an atomic clock depends on two factors: the first is temperature of the sample atoms—colder atoms move much more slowly, allowing longer probe times, the second is the frequency and intrinsic linewidth of the electronic or hyperfine transition. Higher frequencies and narrow lines increase the precision. Atoms and molecules are too small to be counted individually, so a counting unit of “mole” is used. Molar masses are used to convert between mass and moles of atoms or molecules. There are several ways to express the ratio of moles of atoms in a sample.
