THE QUESTION IS...

HOW MANY TYPES OF MOLECULES WITH DIFFERENT MASSES EXIST IN A SAMPLE OF CHLORINE HAS IF THE SAMPLE EXISTS ENTIRELY AS DIATOMIC MOLECULES? EXPLAIN YOUR ANSWER


I HAVE NO IDEA WHAT THIS QUESTION IS TALKING ABOUT AND IM NOT VERY GOOD IN CHEMISTRY...I WAS PUT IN THIS CLASS...AND NOW HAVE NO CHOICE BUT TO DO THE PACKET

THANK U SO MUCH

XOXO

From memory, there are 2 stable isotopes of chlorine (35-Cl and 37-Cl)...maybe the different masses of the diatomic molecules arise from the bonding of different isotopes.  In that case there should be 3 types of molecules (35-Cl + 35-Cl, 37-Cl + 37-Cl and 35-Cl + 37-Cl).

Sev, you're right. There are 2 naturally occurring isotopes of Cl(don't forget, it doesn't have to be stable to occur naturally!): Cl-35 and Cl-37. Two isotopes would be present so you would have 3 possibilities  like Sev said since chlorine is diatomic.
