How do you find the atomic mass of silicon?
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.

What is the relative atomic mass of silicon 28 Silicon 29 and silicon-30?
A sample of naturally occurring silicon consists Si-28 (amu = 27.9769), Si-29 (amu = 28.9765) and Si-30 (amu = 29.9738). If the atomic weight of silicon is 28.0855 and the natural abundance of Si-29 is 4.67%, what are the natural abundances of Si-28 and Si-30?

What is the atomic mass of copper 63 and copper 65?
Copper has two isotopes, 63Cu (69.15%, mass=62.9300 amu) and 65Cu (30.85%, mass = 64.928 amu), and so the respective mole fractions are 0.6915 and 0.3085, resulting in an average atomic weight of 63.55 amu, even though there is not a single atom that weighs 63.55 amu.What is the difference between 28 Si and 29 Si?
Explanation: The abundance of Si-28 is 92.23%. Si-29 is 4.68% and Si-30 is 3.09%. Because most Si atoms have a mass of 28 amu, the average mass of all silicon atoms is very close to 28.

How do you calculate mass number?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
