How many moles of gold are there in 14.2×1023 atoms of gold?
timofeeve [1]

Answer : The correct answer is 2.36 mol of gold

1 mole of any element have 6.022 x 10²³ number of atoms ( Avogadro's number).

So the formula relating mole and number of atoms is given as :

Mole = \frac{given number of atom }{ 6.022 * 10^2^3 atom}    * 1 mol

Plugging value in formula :

Mole = \frac{14.2 *10^2^3 }{6.022 x10^2^3}   * 1 mol

Mole of gold = 2.36 mol
