0.0482 moles Na2SO4 x 6.02x10^23 form.units/mole = 2.91x10^22 formula units
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.
1.42 x 10^-2 mole
The formula for iron (II) sulfate is FeSO4.H2O, and its gram formula unit mass is 169.92. Therefore, 3.52 formula units of this compound have a mass of 598 grams, to the justified number of significant digits.

Copper sulfate does not produce crystals. Copper (II) sulfate pentahydrate (CuSO4•5H2O) does. The formula units are attracted to each other and form a repeating lattice.
Sodium sulfide: Na2S Sodium sulfite: Na2SO3 Sodium sulfate: Na2SO4
The gram formula mass of anhydrous sodium sulfate is 142.04. Therefore, 43 gram formula units* of it has a mass of 43(142.04)6.1 X 103 grams, to the justified number of significant digits. _____________________________ For ionic compounds such as sodium sulfate, the term "formula unit" is preferred to "mole".
How many formula units of sodium acetate are in 0.87 moles of sodium acetat
There is 1.42 x 10^-2 moles of formula units that are in 5.67 g of iron III sulfate.
The answer is 32,4.10e23.
We refer to "molecules" of sodium sulfate as formula units. The formula is Na2SO4. The molar mass is 142 g/mole. And sulfur (S) is 32 out of the entire 142 g. So, percent sulfur is 32/142 (x100%) = 22.5%
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.

Yes, they have one or more SO4-2 units.
1.42 x 10^-2 mole
A same number.
The formula for iron (II) sulfate is FeSO4.H2O, and its gram formula unit mass is 169.92. Therefore, 3.52 formula units of this compound have a mass of 598 grams, to the justified number of significant digits.
