Question

Define molar mass and avogadro constant

Answer 1

Dear Student
Avogadro's constant is defined as the number of particles present in one mole of a substance and is equal to 6.022 X 10²³. The number 6.022 × 10²³ is an experimentally obtained value and is named after the Italian scientist, Amedeo Avogadro. Thus one mole of carbon contains 6.022 × 10²³ atoms of carbon, one mole of H₂O contains 6.022 × 10²³ molecules of H₂O.
