What volume of water in in a bottle of soda?

The volume of water in a bottle of soda varies depending on the size and type of soda. A standard 12-ounce (355 mL) soda typically contains about 90-95% water, which means it has approximately 10.8 to 11.4 ounces (320-340 mL) of water. However, this volume can change based on the specific formulation and added ingredients in different soda brands.
