Answer: 0.0257 moles of [tex]Fe^{3+}[/tex]  and 0.0257 moles of [tex]SO_4^{2-}[/tex]

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

[tex]Molarity=\frac{moles}{\text {Volume in L}}[/tex]

moles of  [tex]Fe_2(SO_4)_3=Molarity\times {\text {Volume in L}}=0.147\times 0.175L=0.0257moles[/tex]

The balanced reaction for dissociation will be:

[tex]Fe_2(SO_4)_3\rightarrow Fe^{3+}+SO_4^{2-}[/tex]

According to stoichiometry:  

1 mole of [tex]Fe_2(SO_4)_3[/tex] gives 1 mole of [tex]Fe^{3+}[/tex]  and 1 mole of [tex]SO_4^{2-}[/tex]

Thus there will be 0.0257 moles of [tex]Fe^{3+}[/tex]  and 0.0257 moles of [tex]SO_4^{2-}[/tex]
