Q: If a mole of moles were digging a mole of holes, what would you see?
A: A mole of molasses!
In chemistry and physics, the Avogadro constant is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. Thus, it is the proportionality factor that relates the molar mass of a compound to the mass of a sample.
So, what is this number and why is it important? The value is 6.022×1023, and it is used primarily in chemistry. Did you ever hear of a mole? No, not those pesky animals in your back yard . . . A mole is the number of atoms or molecules equal to the value of Avogadro’s Number. It’s all about measurement – quantification. Ever hear of a 1 molar solution? That simply is one mole of molecules in 1 liter of solution. So 1 millimolar would be 1/1000 of a mole in 1 liter, and 1 micromolar would be 1/1,000000 mole per liter of solution.
