Most nitrogen atoms have a mass of 14u (hence 28u for N2), but a small
percentage of nitrogen atoms have an extra neutron and thus an atomic mass of 15u. (We
refer to atoms of the same element but with different masses as isotopes of that element.)
Recently, scientists studying isotope data from the Cassini spacecraft have noticed that
the ratio of 15u nitrogen to 14u nitrogen is much larger than it is here on earth. Assuming
that Titan and the earth originally had the same isotope ratios, explain why the ratios
might be different today.
