Question

total charge present on 0.96g of sulphate ion is

Answer 1

The simple answer is that there are 51 atoms and 15 ions in three times the chemical formula for aluminium sulfate.

Answer 2

Answer:

           $SO_{4}$ = 32+64

           = 96

     ∴ Molecules:- $\frac{0.96}{96} = 0.01$ $mol$

         1 mol $SO_{4}$ $1^{-2}$ = 16+4(8)+2

           = 50

         0.01 mol = 0101*50*Na

           =3*1023

Explanation:

• The Lewis structure of $SO_{4}2$- has 32 accessible valence electrons.
• The conjugate base of the bisulfate (or hydrogen sulfate) ion, $HSO_{4}$, which in turn is the conjugate base of $H_{2} SO_{4}$, sulfuric acid, is the sulphate ion, which has an overall charge of 2.
• Sulfate received two electrons to complete its octet, as indicated by the oxidation number of -2, which indicates that its valency is 2. So, $SO_{4}$ has a valency of 2.
• Six valence electrons make up Sulphur. Each oxygen atom has 6 valence electrons. 4 oxygen atoms in sulphate translate to 24 valence electrons. Sulfate has an additional 2 electrons due to its charge of 2.
