◦ 78%
◦ 59%
◦ 46%
◦ 73%
◦ 18%

Question 2

On another planet, boron has two isotopes as follows:

       Isotope                         Mass (amu)                            Natural Abundance (%)

       Boron-10                     10.0129                                   80.00

       Boron-11                     11.0093                                   20.00
