What is the formula for iron (III) sulfide?

The molecule formula is Fe_2S_3 The molecule iron (III) sulfide is an ionic molecule between the metal Iron and the non-metal sulfur In an ionic molecule the formula is determined by balancing the charges on the ions For this case the roman numeral (III) tells us the iron has a charge of +3 or Fe^(+3) The the element sulfur has a charge of -2
