Question

calculation of number atoms and molecular by Avogadro number

Answer 1

Avogadro's number is a very important relationship to remember: 1 mole- 6.022x1023 6.022 x 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
