The Yellow River's mouth is constantly shifting due to erosion and sedimentation. Therefore, providing a precise latitude and longitude for the mouth is difficult.

However, here's what we can say:

* The Yellow River Delta: The Yellow River flows into the Bohai Sea, forming a large delta. This delta is constantly changing, but its approximate location is between 37°30'N and 38°00'N latitude and 118°00'E and 119°00'E longitude.

* The current mouth: To find the most up-to-date location of the Yellow River mouth, you'd need to refer to recent satellite imagery or nautical charts.

Keep in mind that the Yellow River's mouth is a dynamic feature, and its precise location can vary depending on the time of year and recent weather conditions.
