Problem 30P

Use the law of constant composition to complete the table summarizing the amounts of iron and chlorine produced upon the decomposition of several samples of iron(III) chloride.

                                                      Step by step solution

Step 1 of 3

According to the law of constant composition, we know that the ratio of mass of element is the same.

From the given information,

                                 

From the law of constant composition,

For compound B:

                                   

                           

                                           

                                     

As we know,


                                   

                                             

                                                                   

Mass of “Cl” in sample B is 1.427g.
