Problem: Part B. The water found on Earth is almost entirely made up of the 1H and 16O isotopes for a formula of H2O and a molecular mass of 18.0 amu. What is the largest mass that a water molecule could have using other isotopes? Express the mass numerically in atomic mass units.There are three naturally occurring isotopes of hydrogen:protium (ordinary hydrogen): 1H, deuterium (heavy hydrogen): 21H or D, and tritium: 31H or T.There are three naturally occurring isotopes of oxygen: oxygen-16: 168O,oxygen-17: 17O, and 178Ooxygen-18: 188O.
