Use the atomic mass of boron to calculate the relative abundance of boron-10. More questions. Chemistryyyyy helpppp?
What are the percent abundance of two isotopes in a sample of boron having average atomic mass 10. The periodic table of the elements lists the atomic weight of each element, which is the weighted average of the isotope weights based on the abundance of each.
Related Questions Boron occurs naturally as b-10 and b-11, what is the percentage abundance of each isotope?
The U. Setup and work by the first answerer are excellent BUT they calculated the wrong answers. You could easily look up the percent abundance of each isotope in a chemistry book or on the Web, but you may have to calculate the percent abundance by hand, for example, to answer a question on a chemistry test at school. The other isotope must then have an abundance of 100 percent minus x percent, which you express in decimal form as 1 - x.
