Question

The CRC Handbook, a large reference book of chemical and physical data, lists two isotopes of boron (z=5). The atomic mass of 19.78% of boron atoms is 10.013 u. Through a typographical oversight, the atomic mass of the second isotope is not printed. Calculate that atomic mass, taking the tabulated atomic mass of boron as 10.811 u.

Step 1

013 u - Percentage abundance of first isotope = 19.78% - Percentage abundance of second isotope = 80.22% - Average atomic mass of boron = 10.811 u - Atomic mass of second isotope (m2) = ? Show more…
