  • Determine the number of subatomic particles (neutrons and protons) of H and O and relate this to the # of subatomic particles in each choice. 
  • The water molecule with the closest # of neutrons and protons to the regular H2O will appear to be most abundant

Step 1. Determine the # of neutrons and protons of H and O in H2O

  • H has 1 proton and 0 neutron. While O has 8 neutrons and 8 protons
