Calculate the moles of iron (III) chloride used. The concentration was 0.400 g/ml.
I know how to calculate grams to moles..but i dont understand using g/ml
should i just forget about ml and change it to moles?
please help.ty
Calculate the moles?
You would need to know the volume of the iron (III) chloride solution used. If you multiply the volume by the concentration, then you will know the number of grams. Then you can convert to moles using the molecular weight.
Reply:You do have a units problem. You need a volume to calculate a mass from density [g/ml].
mass g = volume ml * density g/ml
