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
