Answer 2

Answer:

126.90447 u

Explanation:

• For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number.
• This is because each proton and each neutron weigh one atomic mass unit (amu).
• By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
