Answer 1

Answer #1

when FeCl₃ dissolved in water it will ionize into

FeCl₃ ------------------> Fe³⁺ + 3 Cl^-

therefore each mole of FeCl₃ will produce 4 moles of ion (1 Fe³⁺ and 3 Cl^-).

therefore total number of ions in 7.88 x 10¹⁹ formula units =

7.88 x 10¹⁹ + (3 x 7.88 x 10¹⁹) = 7.88 x 10¹⁹ + 23.64 x 10¹⁹ = 31.52 x 10¹⁹ moles ions = 3.152 x 10²⁰ moles of ions.
