when iron is heated in a steam of dry chlorine, it produces a chloride that contains 34.5% by mass iron. calculate the empirical formula of this chloride.

  • chemistry -

    assume 100 grams of iron chlride.
    then 34.5 grams of Fe, figure the moles of that.
    Then 65.5 grams of Cl, figure the moles of that.

    Now look at the two numbers. Divide the larger by the smaller: that is the mole ratio between the elements. Empirical ratios reflect the formula.
