explain how avogadro's constant relates to moles of substance
1 mole of a substance contains 6.02 x 1023 particles (molecules, atoms ...). This number (6.02 x 1023) is called the Avogadro's constant. the forumula: n = N / NA (NA is the Avogadro's number / constant; N = number of particles (molecules, atoms...) in the substance) 1 mole of a substance contains 6.02 x 1023 particles (molecules, atoms ...).
