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. 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.
