What is a mole in chemistry?
ChemistryMeasurements
Quick Answer
A mole is a counting unit used in chemistry, equal to about 6.022 × 10^23 particles. It lets chemists connect tiny atoms to measurable amounts of पदार्थ.
The Full Story
The mole is the bridge between the microscopic world of atoms and the measurable world of grams and liters. One mole of any substance contains Avogadro’s number of particles, named after Amedeo Avogadro, with the constant now defined exactly as 6.02214076 × 10^23 entities. Chemists use moles to balance equations and calculate reaction amounts. A mole of carbon-12 has a mass of exactly 12 grams by definition. This unit is foundational to stoichiometry and laboratory chemistry.
