Na2SO4=Sodium 23.0 x 2= 46.0 + S 16.1 + 4 x 16.0= 64.0 total= 126.1 amu vergas, esto es mentira, no le hagas caso al kbron
i = 3 - makes no sense
2 sodium (natrium), 1 sulfur, and 4 oxygen = 7
Add the subscripts, including the implicit "1" for sulfur, to obtain the answer, 7.
7 atoms in total: 2 sodium, 1 sulfur, 4 oxygen.
Though technically speaking since Na2SO4 is an ionic compound it does not have molecules but formula units.

41,1 g of sodium sulfate (Na2SO4, anhydrous) contain 10,455.10e23 atoms.
That depends on the nature of the reaction. For a typical reaction, it will be the subscript following the symbol of the element multiplied by the coefficient. For example, in Na2SO4 there will be 2 Na atoms, 1 S atom and 4 O atoms. If the reaction was 2 Na2SO4, there would be 4 Na atoms, 2 S atoms and 8 O atoms.
Symbols are the chemical symbols of elements.Number are the number of a specific atom in the molecule or formula unit. For example: Na2SO4- Na, S, O are the chemical symbols of sodium, sulfur and oxygen- 2 is the number of sodium atoms in the formula unit; 4 is the number of oxygen atoms in the formula unit
First.Get moles sodium sulfate.5.35 grams Na2SO4 (1 mole Na2SO4/142.05 grams)= 0.0377 moles Na2SO4-------------------------------------Second.Molarity = moles of solute/Liters of solution ( 330 mL = 0.33 Liters )Molarity = 0.0377 moles Na2SO4/0.33 Liters= 0.114 M Na2SO4=============
25.0 grams Na2SO4 ( only way this compound is possible ) 25.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams) = 0.176 moles Na2SO4 -----------------------------

Full formal set up. 2.88 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(6.022 X 1023/1 mole Na2SO4)(1 mole Na2SO4 atoms/6.022 X 1023) = 0.020 moles of sodium sulfate atoms ------------------------------------------------------( you can see the last two steps are superfluous )

Na2SO4
none
A salt containing two atoms of sodium; for example disodium sulfate - Na2SO4.
Na2SO4Three different types of atoms.2 atoms of sodium.1 atom of sulfur.4 atoms of oxygen.This compound is called,sodium sulfate.
You probable think to sodium sulfate, Na2SO4. Na2SO4 has: 7 atoms total - 2 sodium, 1 sulfur and 4 oxygen. 2Na2SO4 (two molecules) have 14 atoms.
in 0.25 moles there are 1.505*10^23 molecules (1 mole of any element=6.023*10^23 molecules)
Symbols are the chemical symbols of elements.Number are the number of a specific atom in the molecule or formula unit. For example: Na2SO4- Na, S, O are the chemical symbols of sodium, sulfur and oxygen- 2 is the number of sodium atoms in the formula unit; 4 is the number of oxygen atoms in the formula unit
sulfuric acid + sodium hydroxide ---> sodium sulfate + water
