The number of particles the compound consists of is 7.65 × 10²⁴.
It is given that
no of moles n = 12.7
as we know the formulae for the number of particles
N=n× Nₐ
where Nₐ is Avogadro's Number.
n is the number of moles.
<h3>what is Avogadro's Number?</h3>
Avogadro's Number is the number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 10²³.
Therefore, the number of particles N= 12.7 × 6.02214076 × 10²³.
N=7.65 × 10²⁴
