Số mol được tính theo công thức:

\(n=\dfrac{N}{NA}\)

Trong đó:

N là số nguyên tử (trong trường hợp này là 3,011x10²³ )

NA là số Avogadro, khoảng 6,022x10²³ nguyên tử/mol.

Áp dụng vào công thức:

n=\(\dfrac{3,011x10^{23}}{6,022x10^{23}}\approx0,500mol\)

Vậy số mol nguyên tử Cu tương ứng với 3,011x10²³ nguyên tử là khoảng 0,5 mol.
