Question

calculate the number of p atoms in one mole of p4

Answer 1

Hello friend!!
Rajdeep here.....

1mole of phosphorus means 6×10²³ molecules of phosphorus.
1 molecule of phosphorus means 4 atoms of phosphorus (P4)

Hence, from the above , we get....
1 molecule of P4 contains 4 atoms.
Hence, 6×10²³ molecules of P4 contain 4 × 6 × 10²³ atoms = 24×10²³ atoms = 2.4×10²⁴ atoms of phosphorus.

Thanks!!
