Question

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

Answer 1

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

Answer 2

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 = (given number of atom )/( 6.022 * 10^2^3 atom) * 1 mol`

Plugging value in formula :

`Mole = (14.2 *10^2^3 )/(6.022 x10^2^3) * 1 mol`

Mole of gold = 2.36 mol
