Question

One mole of an element contains which of the following?

Answer 1

B. 6.02 x 10^23 atoms

Answer 2

Answer : The correct option is, (B) $6.02\times 10^{23}$ atoms.

Explanation :

Mole : It is defined as the amount of substance that contain the same number of units as there are atoms present in exactly 12 grams of carbon-12.

Avogadro's number : It is defined as the number of atoms molecules present in a mole of any substance.

The Avogadro's number is represented as, $6.022\times 10^{23}$

The relationship between a mole and Avogadro number are :

As, 1 mole of a substance contains $6.022\times 10^{23}$ number of atoms, molecules or ions.

Hence, the correct option is, (B) $6.02\times 10^{23}$ atoms.
