I apologize for any confusion. The caffeine content in Coca-Cola can vary slightly depending on the specific formulation and country where it's sold. However, on average, a 12-ounce (355 ml) can of Coca-Cola Classic contains approximately 34 milligrams of caffeine.
It's important to note that this value is an average and may vary slightly depending on factors such as the specific recipe used by the bottler or manufacturer, regional variations, and any changes in formulations over time.
If you're concerned about your caffeine intake, it's essential to be aware of the caffeine content of the specific Coca-Cola product you're consuming and to moderate your intake accordingly.
