3. Boron (B; Z=5) has two naturally occurring isotopes. Find the percent abundances of ¹0B and ¹1B given these data: atomic mass of B=10.81 amu, isotopic mass of 10B=10.0129 amu, and isotopic mass of ¹¹B=11.0093 amu. (Hint: The sum of the fractional abundances is 1. If x=abundance of ¹0B, then 1-x= abundance of 11B.)
