The mole and Avogadro's number (video) / Khan Academy ~ In an actual chemistry practice, finding out the moles of a substance might actually be the most useful thing, but if you wanted to find out the actual atoms of germanium that we're dealing with, we will just multiply by the number of atoms you have per mole. And, this is going to be true for any element. For every mole, you have Avogadro's number of atoms. And, we're going to approximate that .
Chemistry - dummies ~ Many calculations that you make in chemistry will involve unit conversions (for example, between meters and millimeters, or between meters and inches).
