6. naturally occurring strontium consists of four isotopes, sr-84, sr-86, sr-87 and sr-88,
whose atomic masses are 83.9134, 85.9094, 86.9089 and 87.9056 amu respectively. the
most abundant isotope is sr-88 which accounts for 82.58% of naturally occurring
strontium and the least abundant isotope is sr-84 which accounts for 0.56% of naturally
occurring strontium. given that the observed atomic mass of strontium is 87.62 amu,
calculate the percentages of sr-86 and sr-87 in nature.
