The percent composition of hydrogen in sucrose (C₁₂H₂₂O₁₁) is 6.48%.
Sucrose, commonly known as table sugar, is a disaccharide formed from glucose and fructose. To determine its percent composition by mass, one would ideally perform calculations based on the molar mass of each element and the compound. However, in this case, we can directly reference the provided information.
The reference states: "A more complex example is sucrose (table sugar), which is 42.11% carbon, 6.48% hydrogen, and 51.41% oxygen by mass."
Therefore, the percent composition of hydrogen in sucrose is definitively 6.48%.
