9.56 x 1020 (9.56e+20) molecules of chlorine (Cl2) is what mass in grams?
What happens when Chlorine molecules, Cl2, mix with water? Pick the best answer. They would dissolve well because chlorine molecules are polar. They would dissolve well because chlorine molecules are not polar. They would dissolve poorly or not at all because chlorine molecules are polar. The would dissolve poorly or not at all because chlorine molecules are not polar. The would dissolve well because chlorine molecules are ionic.
