Which part of the Constitution gives the Federal Government the right to pass abortion legislation ?

The 14th Amendment.

You're wrong. This abortion ban has nothing to do with the 14th Amendment. It's commerce clause legislation, nothing more.

[Mr. Silverback]

Whether the congresscritters explicitly based their bill on the 14th Amendment or not, it clearly grants them the authority to take this action, and not a single thing about it would be different if they had based it on the 14th.
