Question

chemistry some based on average atomic mass

I ONLY NEED SOLVING THE ANSWER IS 11.01 HOW PLS TELL

question:- atomic mass of 10B and 11B are 10.013 and X If the percentage abundance of these isotopes are 19.1 and 80.9 resp. average atomic mass of boron is 10.81 find the mass of X​

Answer 1

Explanation:

The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of atoms of that element that are of a given isotope). Average atomic mass = f1M1 + f2M2
