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.
