The number of particles the compound consists of is 7.65 × 10²⁴.
It is given that
Number of moles n = 12.7
As we know the formula for the number of particles:
N=n× Nₐ
Where Nₐ is Avogadro's Number, n is the number of moles.
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.
So, the number of particles:
N= 12.7 × 6.02214076 × 10²³.
N=7.65 × 10²⁴
Therefore, the number of particles the compound consists of is 7.65 × 10²⁴.
