Question
Strotium has 4 naturally occuring isotopes. Theirnatural abundances and atomic masses are: ISOTOPE MASS NATURAL ABUNDANCE Strotium 84 83.9134 .50 Strotium 86 85.9094 9.90 Strotium 87 86.9089 7.0 Strotium 88 87.9056 82.60 Show that the atomic weight of Strotium is 87.62? Strotium has 4 naturally occuring isotopes. Theirnatural abundances and atomic masses are: ISOTOPE MASS NATURAL ABUNDANCE Strotium 84 83.9134 .50 Strotium 86 85.9094 9.90 Strotium 87 86.9089 7.0 Strotium 88 87.9056 82.60 Show that the atomic weight of Strotium is 87.62?Explanation / Answer
The simplest way to do this question is to put weight on mass basedon natural abundance: So, Atomic weight of strontium = 83.9134 x 0.005 + 85.9094 x 0.099+ 86.9089 x 0.07 + 87.9056 x 0.826 = 87.62 Hope this helps!
