Boron ocuursas b10 and b11 in natuer average atimic mass of boron is 10.804 what is the natural abundance of b11 isotopes |
|
Answer» Answer: b¹1 has more abundance in naturw with 80.4% % abundance of b-10 be x % abundance of b-11 be (100-x) 10*x+11(100-x)/100=10.804 10x+1100-11x=1080.4 -x=1080.4-1100 =19.6 % abundance of b-10 be 19.6% % abundance of b-11 be (100-19.6)=80.4% |
