QUESTION 10
The 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 was
10.3318 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 the
fractional 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.
