How many atoms does one mole of Phosphorus contain?

We need to calculate how many atoms does one mole of Phosphorus contain. First let us know about the Phosphorous atom.

• Phosphorus is a highly reactive element.
• The symbol of phosphorus is ‘P’
• The atomic number is 15
• The atomic mass number is 31.

Number of atoms

Phosphorus exists as a tetratomic molecule. Hence, there are 4 atoms of phosphorus in one molecule of phosphorus.

1 mole of P₄ = 6.022  × 10²³ molecules of P₄(Avogadro number)

1 molecule of P₄ = 4 atoms of P

1 mole of P₄ = 4 × 6.022  × 10²³ atoms of P

1 mole of P₄ = 2.4088 × 10²⁴ atoms of P

= 24.088 × 10²³ atoms of P

Answer

24.088 × 10²³ atoms of P are present in
