Question

The no. of atoms present in 0.1 mole of P4 are

Answer 1

Answer:

2.4×10^23

Explanation:

as we know no of molecules= no of moles into avagadro's no

0.1× 6.022×10^23

=6.022×10^22

for finding no of atoms in p4

p4=4×6.022×10^22

=24.0810^22

=2.4 ×10^23

Answer 2

Answer:

The no of atoms is = 24.092 × 10²²

Explanation:

An atom is the least unit into which matter can be divided without the release of electrically charged particles. It also stands for the smallest unit of matter that has the distinctive properties of a chemical element.

The number of molecules = number of moles × Avogadro's constant.

no of molecules = 0.1 × 6.023 × 10²³

= 6.023 × 10²²

in P4

no of atoms = 4 × no of molecules

Hence,

no of atoms = 4 × 6.023 × 10²²

= 24.092 × 10²².
