Answer to Question #52442 in Inorganic Chemistry for kayla
Solutions of iron (III) chloride, FeCl3, are used in photoengraving and to make ink. This compound can be made by the following reaction:
2Fe + 3Cl sub 2, reaction arrow, 2FeCl sub 3.
How many grams of Fe are needed to combine with 4.5 moles of Cl2?
From the reaction: 3 moles of Cl2 react with 2 moles of Fe, So 4,5 moles of Cl2 will react with X moles of Fe. X=4,5*2/3=3 moles of Fe Molar mass of(Fe)=56 g/mole, so m(Fe)=3*56=168 grams Answer: 168 grams
