To determine the number of hydrogen atoms in the formula of sodium lauryl sulfate (C12H25NaO4S), we can break down the molecular formula:

• C12: There are 12 carbon (C) atoms.
• H25: There are 25 hydrogen (H) atoms.
• Na: There is 1 sodium (Na) atom.
• O4: There are 4 oxygen (O) atoms.
• S: There is 1 sulfur (S) atom.

The specific focus here is on hydrogen. From the formula, we see there are 25 hydrogen atoms.

So the correct answer is:
