Serration is an uncommon mod, therefore if you look in the table above you'll find that Rank 10 requires 4096 energy. An uncommon mod comes with 8 energy standard, so you'd  need 512 Serration mods (Unranked) to level the mod from 9 to 10. As far as cost in credits, that would vary depending on whether you used fusion cores or not. That said, no one in their right mind ranks Serration beyond it giving 135% extra damage. Taking a mod beyond Rank 8 is insanely difficult to do.
