Mole (unit) - Simple English Wikipedia, the free encyclopedia
Mole is the SI unit used to measure how many molecules or atoms there are. One mole is around 600 sextillion molecules. Scientists use this number because 1 gram of hydrogen is around 1 mole of atoms. The exact value of one mole is 6.022 140 78 × 10 23. This number comes from experiments with carbon because it's easy to work with. [1] [2]
