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
