Mass of molecular clouds versus stars

Hey.

Is there a sort of percentage known of how much mass in the universe is in molecular clouds compared to stars. I need this for a work I am doing. Thanks

The two are about even. Look up the NASA Astrophysical Database Service and have a look at the primary literature yourself for more details.
