Key Takeaways: Mole in Chemistry The mole is anSI unitused to measure the amount of any substance. The abbreviation for mole is mol. One mole is exactly 6.02214076×1023particles. The "particles" could be something small, like electrons or atoms, or something large, like elephants or stars....
The mole ratio compares the number of moles in a balanced equation. This is the comparison between the coefficients in front of the chemical formulas. If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species. ...
