Guida verificata passo dopo passo1
Understand that one mole of any substance contains Avogadro's number of particles (atoms, molecules, ions, etc.).
Recall the value of Avogadro's number, which is approximately \(6.022 \times 10^{23}\) particles per mole.
Since the problem asks for the number of atoms in one mole of gold (Au), recognize that the number of atoms is equal to Avogadro's number.
Note that the atomic mass of gold (197) is not directly needed to find the number of atoms in one mole; it is used for mass calculations.
Conclude that one mole of gold contains \(6.022 \times 10^{23}\) atoms, which is Avogadro's number.
