Corey is analyzing samples of two compounds Corey is analyzing samples of two compounds. Through scientific experimentation, she has determined that the compounds are types of CFCs, or chlorofluorocarbons, which are environmental pollutants that contain the elements carbon (C), chlorine (Cl), and fluorine (F). She now wants to determine if the two samples have the same concentration of the elements Cl and F. The table below shows the mass, in grams (g), of Cl and F in each sample. Which of the following is the best explanation of Corey's data? A   a.  Both compound samples have more chlorine than fluorine. b.  Sample 1 has a greater concentration of fluorine than Sample 2. c.  Sample 1 has a greater concentration of chlorine than Sample 2. d.  Both samples have the same concentration of chlorine and fluorine.
