Mole
The mole is the SI base unit used that scientist use to measure a substance. But it can't be used to measure just anything. It is in better use to measure something along of the lines of the surface area of the earths depth. The mole of anything contains 6.0221367x 10^ 23 representative particles such as atoms, molecules, formula units, electrons or ions. The number 6.0221367 is called Avogadro's number because in 1811 Amedeo Avogadro determined the volume of one mole of a gas. So basically he started the mole. The other day we conducted a lab where we had to figure out what element it was by figuring out the atomic mass and we were only given the number of moles. Then we weighed the number of grams in each cup. After getting the grams, we took the number of grams divided by the number of moles and got the atomic mass. Then we basically knew what element it was.
