Question

Calculate the number of atoms of each element and the total number of atoms contained in 2.50 moles of Al2(SO4)3.

Answer 1

Answer:

15.05 * 10^23 atoms are present in 2.50moles of Al2(SO4)3

Explanation:

To solve this question, the Avogadro equation is used.

Number of moles (n) = number of atoms (N) / Avogadro number.

n = N / 6.02*10^23

So therefore;

2.50moles = N / 6.02* 10^23

N = 6.02* 10^23 * 2.50

N = 15.05* 10^23 atoms.
