How many sulfur atoms are present in 25.6 g of al2(s2o3)3

Given the mass of =25.6 g

The molar mass of =390.35g/mol

Converting mass of to moles:

Converting mol to mol S:

Converting mol S to atoms of S using Avogadro's number:

1 mol =

Sulfur is a chemical element with symbol S. It is found in the in the group 16. It has atomic number 16 and atomic mass as 32 units. In the compound there are 2.37 x atoms of sulfur are present.

Given that,

Now, converting mass of into moles, we get:

Similarly, for sulphur:

From the Avogadro's number, we know that,

Now, 0.3936 moles of sulphur will have:

Therefore, the number of atoms of sulphur in the compound is 2.37 .
