Question

How many moles of gold are there in 14.2×1023 atoms of gold?

Answer 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

Answer 2

You would use mole constant which is 6.02x10^23 so your answer would be 14.2x10^23/mole constant
