A 500 mg sample contains FeCl3 & MgCl2. Ammonia was added to the sample to precipitate the chlorides. The filtrated sample was then heated to form 235.59 mg of oxides. 1. Determine the %Fe in the sample if it contains 5mg of inert matter. 2. Calculate the mass of MgCl2 in the sample. 3. How many milligrams of iron oxide was formed after heating.
