Question

calculate number of atoms in 23 moles of gold​

Answer 1

Answer:

1 mole = 6.022 *10^23 atom

so. 23 moles of gold = {23 * (6.022 *10^23)}

= 138.56 * 10^23 atoms.

Explanation:

Avogadro's number is a crucial equation to remember: 1 mole = 6.022 *10^23 atoms, molecules, protons, and so on. Multiply the molar amount by Avogadro's number to convert from moles to atoms. Divide the atom amount by Avogadro's number to convert from atoms to moles (or multiply by its reciprocal).
