If 23.5 grams of iron chloride are produced how many grams of iron did you start with?

• chemistry -

Write the equation and balance it.

Convert 23.5 grams iron chloride (did you mean iron(II) chloride or iron(III) chloride?)

Using the coefficients in the balanced equation, convert moles iron chloride to moles iron.

Now convert moles iron to grams. g = moles x molar mass.

• chemistry -

moles iron chloride = 23.5 g/molar mass.
