I rounded up to 1.47 X 10^24 atoms of Sulfur in 78.4 grams Sulfur78.4 grams X (1 mole S/32.07 g S) X (6.02 X 10^23 atoms S/ 1 mole) = 1.472 X 10^24 atomTaking significant digits into account (3 sig. figs.), I get 1.47 X 10^24 atoms S
no of atoms = weight of the given substance/ atomic mass of substance according to the question:- no of atoms = 3/32 answer
The formula unit for iron (III) sulfate is Fe2(SO4)3. This formula shows that there are two iron atoms, three sulfur atoms, and twelve oxygen atoms, totalling 17 atoms altogether.
1.659 [grams] / 47.998 [grams / mol] * 6.02214179(30)×1023 [molecules / mole] * 3 [atoms / molecule]. A bunch.
Aluminium sulfate is Al2(SO4)3 and has two aluminium, three sulphates and 12 oxygens. So there are a total of 17 atoms.

Aluminum sulfide is Al2S3, which has 3 sulfur atoms per formula unit. 1.10mol means 1.10(6.02x1023), which is 6.62x1023 formula units. Multiple that by 3 to get your sulfur atoms: 6.62x1023(3) = 1.99x1024 sulfur atoms.
4 atoms (1 of Sulfur and 3 of Oxygen)
3 atoms... 2 atoms for H (Hydrogen) and 1 atom for S (Sulfur) 2 + 1 = 3!!
The Atomic Mass of one (1) atom of sulfur is 37.02. The atomic mass of three (3) atoms of sulfur is 96.21. 32.07 * 3 = 96.21
The chemical formula for hydrogen sulfide is H2S. There are two hydrogen atoms and one sulfur atom for a total of three atoms.
Ferric sulfide has 2 Fe (iron) atoms and 3 S(sulfur) atoms. So totally 5 atoms.
Multiply the coefficient times the subscript for each element. For 3Na2SO4, there are a total of 6 sodium atoms, 3 sulfur atoms, and 12 oxygen atoms.
