#Complete the table. Then analyze the data to determine if Compounds I and II are the same compound. If the compounds are different, use the law of multiple proportions to show the relationship between them: Analysis Data of Two Iron Compounds

Compound Total Mass (g)/Mass Fe (g)/Mass O (g) /Mass Percent Fe/Mass Percent
I 75.00 / 52.46 / 22.54 / ? / ?
II 56.00 / 43.53 / 12.47 / ? / ?

answer; /// i do believe that the correct answer is (a) boiling
