What is the SI unit used to measure molecules and atoms?

Q: What is the SI unit used to measure molecules and atoms?


A: The SI unit used to measure molecules and atoms is mole.

Q: How many molecules are in one mole?


A: One mole contains around 600 sextillion molecules.

Q: Why do scientists use this number?


A: Scientists use this number because 1 gram of hydrogen is equivalent to 1 mole of atoms.

Q: What is the exact value of one mole?


A: The exact value of one mole is 6.02214078×1023, which was named after Avogadro who invented it.

Q: Is it practical to measure most tasks using moles?


A: No, it is not practical to measure most tasks using moles as the value is so massive that one mole of grapefruits would be as big as the earth.

Q: How are different molecules and atoms measured?


A: Different molecules and atoms are measured in amu (atomic mass units).

Q: How does amu relate to grams per mole? A: One amu is equal to one gram per mole, meaning if an atom has a mass of one amu, then one mole of this atom weighs one gram.
