Dec 01, 2020 · How do you determine isotopes? Isotopes are identified by their mass, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons). How can you tell isotopes of the same element apart?. Let us know something about the isotopes of hydrogen: There are three isotopes of hydrogen and these are protium, deuterium, and tritium. All three of them have the same number of protons, but the numbers of neutrons differ. In protium the number of neutrons is zero, in deuterium, it is one and in tritium, the number of neutrons is two. To calculate this, take the number of each of the isotopes divided by the total and multiply by 100 to give you the percent abundance of each. There should be 6 calculations below. Ex:78/332X100=23.49% C. To get the mass contribution for each isotope you must multiply the Percent abundance by the average mass of each isotope..
