QUESTION 10The element boron has twa naturally occurring isotopes with masses of 10.0129 amu and 11.0093 amu. What would be the fractional abundance of the first isotope. if the atomic weight was10.3318 amu?Key Concept The mass on the periodic table of each element is a weighted average of the mass from all of the isotopes and is determined by: AM obs fAM+f2AM 2 where fis thefractional abundance of a given isotope. The abundance of isotope 1 is 100f 1.Also note that the sum of the fractional abundances equals one i.e. f1+121.

The atom consists of 3 subatomic particles: Protons: They are positively charged particles present…

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")
