Detailed explanation-1: -My high school chemistry textbook put it this way: If you had one mole of marbles-6.02x1023 marbles, that is-and you spread them all over the entire surface of the Earth, you’d produce a layer that’s about three miles thick. I’ve read that they also call that number Avogadro’s constant.
Detailed explanation-2: -Moles in (3.52 X 10^24) molecules of water. 3.52 x 10^24 molecules x ‘1mol/6.02 x 10^23 molecules = 5.85 moles of H2O.
Detailed explanation-3: -Updated On: 27-06-2022 Thus, 9.033×1024 atoms of helium are 15 moles of atoms.
Detailed explanation-4: -The MOLE (mol) is a unit of measurement that is the amount of a pure substance containing the same number of chemical units (atoms, molecules etc.) as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 1023).
