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%

How many electron's are transferred in the ionic bond between sulfur and barium?
Two electrons are transferred to sulfur from barium to form barium sulfide.
How many numbers and type of atoms are present in hydrogen sulfide?
Each molecule of hydrogen sulfide contains two hydrogen atoms and one sulfur atom.
How many sulfur molecules are there in 6.35 moles of S?
6,35 moles of S contain 38,24059444195.10e23 sulfur atoms.
How many moles are in 4.5X1028 molecules of sodium fluoride NaF?
4,5.10e28 molecules of sodium fluoride NaF are equal to 0,745.10e5 moles.
Why do photosynthetic sulfur bacteria use hydrogen sulfide?
I am not entirely sure what photosynthetic sulfur bacteria would be, but many chemosynthetic bacteria use hydrogen sulfide as a source of energy (a good example is the ecosystems of underwater sea vents) photosynthetic bacteria rely (as their name suggests) on light from the sun as the source of their energy
How many electrons does an atom of sodium lose when it forms a bond how many electrons does an atom of sulfur gain when it forms a bond?
Sodium loses one electron to form a Na+ ion. Sulfur gains two electrons to form a sulfide ion, S2-.
How many prototns are in sulfide?
There are 16 protons in the sulfide ion, which is similar to the sulfur atom.
How many electrons does a sulfur atom gain when it becomes a sulfide ion?
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
What element can combine with sulfur to make an ionic compound?
Many metals form ionic sulfides containing the S2- ion, , for example sodium, Na2S sodium sulfide. Iron forms a sulfide, FeS, iron(II) sulfide and a disulfide, containing the S22- ion, iron, iron(II) disulfide, FeS2 , "fools gold"
How many moles are there in 73.5 g of sodium sulfide?
The formula mass of sodium sulfide, Na2S, is 2(23.0)+32.1=78.1 Amount of sodium sulfide = 73.5/78.1 = 0.941mol
How many ionic charge does sodium sulfide has?
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
How many sulfur ions are joined to each zinc ions in the compound zinc sulfide?
The chemical formula of zinc sulfide is ZnS - one sulfur atom.
How many atoms of sulfur are in one molecule of iron sulfide?

What charge is for sulfur?
Sulphur (also sulfur) is an element. It can be both uncharged and charged. In pure form sulfur is uncharged. As sulfide ions is has charge -2. In many molecules (like the amino acid custeine) and polyatomic ions (like the sulfate ion) sulfur does not have a formal charge, but can have many different states of oxidation.
Hydrogen sulfide has how many atoms?
Hydrogen Sulfide has a total of three atoms. Hydrogen has two, and Sulfur has one. H2S.
How many grams of sodium sulfide are formed if 1.90 of hydrogen sulfide is bubbled into a solution containing 2.53 of sodium hydroxide assuming that the sodium sulfide is made in 91.0 yield?
The equation for the reaction specified is 2 NaOH + H2S -> Na2S + H2O. Therefore, if the yield were 100 %, two formula masses of sodium hydroxide are required to produce one formula mass of sodium sulfide. The gram formula mass of NaOH is 40.00 and that of sodium sulfide is 78.04. The specified number of grams of sodium hydroxide corresponds to 2.53/40.00 or 0.06325 formula masses and therefore would provide half this many formula masses of sodium sulfide, for a mass of (0.06325)(78.04)/2.000 or 2.568 grams of sodium sulfide. Since the yield is specified as 91.0 %, the actual amount of sodium sulfide produced is 2.25 grams, to the justified number of significant digits.
