Solution

6. In order to find the mass produced of Fe₂S₃, we need to find the number of moles of FeCl₃.

Concentration of FeCl₃ = 0.224 M

Volume of FeCl₃. = 125 ml

Number of moles of FeCl₃ = 0.224 * 0.125 = 0.028 moles

Since the stoichiometric ratio of FeCl₃ to Fe₂S₃ is 2:1, the number of moles of Fe₂S₃ is half of FeCl₃.

Number of moles of Fe₂S₃ = 0.028/2 = 0.014 moles

Molecular mass of Fe₂S₃ = 207.9 grams/mol

Mass of Fe₂S₃ produced = 0.014 * 207.9 = 2.91 grams.
