1.	Boron occurs in nature in the form of two isotopes and in ratio of 81% and 19% respectively. Calculate its average atomic mass.
Answer» ccurs naturally in two isotopic forms. The natural abundance of BORON-10 is 19.9% with 10.013 AMU and Boron-11 is 80.1% with 11.009 amu.The atomic weight of Boron is 11In ORDER to CALCULATE the average atomic weight,
