Boron
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
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.
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
(mass of A) x (%of A) + (mass of B) x (% of B) + (mass of C) x (% of C)
The atomic mass of boron-11 (B-11) can be calculated by setting up an equation based on the given average atomic mass of boron and the known atomic mass and abundance of boron-10 (B-10). Since the average atomic mass is a weighted average of the isotopes, the equation would be: (mass of B-10 * % abundance of B-10) + (mass of B-11 * % abundance of B-11) = average atomic mass of boron. Solving this equation will give you the atomic mass of B-11.

Atomic mass number of boron(B) - 11
The true statements are A and B. Statement A is called Avogadro's number and represents the number of particles in one mole. Statement B refers to the molar mass, which is the mass of 1 mole of a substance expressed in grams, and is numerically equal to the atomic mass in atomic mass units (amu).
The atomic mass of Boron (B) is 11 but to be more accurate, the atomic mass is 10.81.
