How water is in 1 can diet Dr Pepper?

A can of Diet Dr Pepper, like most soft drinks, primarily consists of carbonated water. Typically, a 12-ounce (355 ml) can contains about 90-95% water, which translates to roughly 10-11 ounces of water. The remaining volume consists of artificial sweeteners, flavorings, and carbonation, contributing to the drink's unique taste without adding calories.
