SOLVED: Active Exercise3. Calculate the atomic mass of boron. Boron has 2 isotopes. The first isotope has a natural abundance of 19.9% and a mass of 10.0129370 amu and the second isotope has a natural abundance of 80.1% and a mass of 11.0093055 amu:4. Naturally occurring lithium is composed of two isotopes: 7.59% abundant at 6.0151224 amu and 92.41% abundant at 7.0160041 amu: Determine the atomic mass of lithium

the natural abundance of one isotope of an element is 75 with exact mass 300 amu and the second is 25 with exact mass 310 amu what is the average atomic mass of the element 76106
