MOLAR MASS :

1 molecule of P has 4 P atoms.

So molar mass equals four times atomic mass, =4 x 24= 196 g/mol

(in the photo, the unit of molar mass is g/mol, I have wrongly written it as u)

NO OF ATOMS IN 1 MOLE OF P MOLECULES:

One mole of element has avogadros no of atoms which is 6.022 x 10²³ atoms

Since 1 molecule has 4 P atoms,

total atoms is

4 x 6.022 x 10²³ atoms

MASS OF ONE MOLE OF P ATOM:

= atomic mass

=24 g

NO OF MOLECULES IN ONE MOLE OF P MOLECULE:

One molecule has avogadros no. of molecule.

Hence, for 1 molecule of P, no. of molecules

=6.022 × 10²³ molecules
