Answer:
26 hydrogen atoms
Explanation:
Let us look at the formula presented for Adrenalin carefully. We will discover that the formula written there is 2C9H13NO3.
This means that that's there are 18 carbon atoms, 26 hydrogen atoms 2 nitrogen atoms and 6 oxygen atoms in the formula shown above.
This is so because the 2 written before the symbols of the elements must multiply the subscript of each element in order to obtain the number of atoms of that element present in the compound as shown.
