Answer 1

ANSWER:-

Avogadro’s number tells us the number of particles in 1 mole (or mol) of a substance. These particles could be electrons or molecules or atoms. The value of Avogadro’s number is approximately 6.022140857×1023 mol−1.

Eg:-

if you wanted to know the number of particles in 3 moles of a substance, the value would be:

= 3 x 6.023 x 1023

= 1.81 x 1024 particles
