An unmanned space shuttle mission brings samples back to Earth from Mars. Working with samples from mars, you discover that the isotope abundances on Mars are different from on Earth. You are tasked with calculating the average atomic mass (weight) of nitrogen that exists naturally on Mars. You find that the abundance of nitrogen-15 (atomic mass of 15.000 amu) on Mars is 11.639%, and the rest of the nitrogen (abundance = 100% - 11.639%) is nitrogen-14 (atomic mass 14.003 amu). Using that information, what is the average atomic mass (in amu) of nitrogen on Mars? (answer should have 3 decimal places - only input numbers, not "amu")
