You need to specify which sugar you're asking about! There are many different types of sugars, each with a different chemical formula.

Here are a few examples:

* Glucose (C6H12O6): Has 12 hydrogen atoms.

* Fructose (C6H12O6): Has 12 hydrogen atoms.

* Sucrose (C12H22O11): Has 22 hydrogen atoms.

Please let me know which sugar you're interested in, and I can tell you how many hydrogen atoms it has!
