Quizplus · Accepted Answer

Adrenaline, with the molecular formula C9H13NO3, consists of 9 carbon (C) atoms, 13 hydrogen (H) atoms, 1 nitrogen (N) atom, and 3 oxygen (O) atoms. The total number of protons is calculated by adding the atomic numbers of these elements: Carbon (6 protons) x 9 = 54, Hydrogen (1 proton) x 13 = 13, Nitrogen (7 protons) x 1 = 7, and Oxygen (8 protons) x 3 = 24. Adding these together gives 54 + 13 + 7 + 24 = 98 protons.
