Respuesta :

calculate the molar mass of Fe + 3(Cl)

that is your total mass

percent composition of FeCl3

mass % Fe = molar mass FE / total mass X 100 = %

mass % 3Cl = molar mass 3Cl / total mass X 100 = %

that is percent composition

Hope it’s help !!!!

Composition of iron in FeCl3​.

Iron III chloride is an inorganic compound that is a common compound of iron and is known as ferric chloride and has a plus-three oxidization state. It has a melting point of about 307.6 °. It is used as a form of drying reagent, used in wasted water treatment and same medical devices.

Thus the answer is FeCl3 is +3.

  • The steps that involve in the formation and composition f the iron in FeCl 3 is  by a group of seven elements that have a capacity of -1, thus the capacity of Chlorine is -1
  • The second step involves the summation of the oxidation no of the neutral compound that is zero, thus Fe + 3 × Cl = 0.

As we combining capacity of Iron.

  • y + (-1 × 3) = 0 y - 3 = 0 y = +3
  • Thus the capacity of iron is +3.
