No, the partition there does not have a UUID.  Run fdisk, create a partition,
dd if=/dev/zero of=/dev/sda4


You'll see no UUID, as the partition does not provide a UUID, and there's
nothing on it to provide a UUID.  Format it, or make some swap space or
whatever, and you get a UUID.

You never mount a partition, only a filesystem.  The partition merely points
you to where the filesystem is.
