What is the atomic mass of B if 19.9 percent of all B atoms have a mass of 10.01 amu and 80.1 percent have a mass of 11.01 amu?
Given : Atomic mass of B = 10.01 amu , % = 19.9 let it be A Atomic mass of B = 11.01 amu , % = 80.1 Solution : A and B are approximately in the ratio 1:4. Isotopic mass = [(proportion of A X at. mass of A) + (proportion of B X at. mass of B)] / 4 = [(1 X 10.01) + (4 X 11.01)] / 4 = (10.01 + 44.04) / 4 = 54.05 / 4 Isotopic atomic mass = 13.512 amu ---- Therefore, isotopic atomic mass of B is = 13.512 amu.
What is the average atomic mass of an element with isotopes a b and c?
(mass of A) x (%of A) + (mass of B) x (% of B) + (mass of C) x (% of C)
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
Which element has a greater atomic mass A or B?

What is the atomic weight of bromine?
The atomic mass of Boron (B) is 11 but to be more accurate, the atomic mass is 10.81.
What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
