Question

Quizplus · Accepted Answer

This is the definition of a mole, a unit of measurement that represents a certain number of particles (atoms, molecules, ions, etc.) equal to Avogadro's number (6.02 x 10^23), which is the number of atoms in one mole of any element. Therefore, one mole of any element will have a mass equal to its average atomic mass expressed in grams.
