Which of the following lists includes only molecules? fe8 co mg he h20 no2 co fe o2 nacl n2 h20

The only list containing molecules is list #4

NaCl, N2, and H2O are all made up of more than one element, making them molecules. The other lists contain an element. Mg, He, and Fe are elements, not molecules.

Hope this helps!
