The Atomic Mass is the number of protons plus the number of neutrons.
The number of protons is identical to the atomic number (as well as electrons, but these don't matter right now). So, let's take helium. It has 2 protons and 2 neutrons, therefore the atomic mass # of helium is 4. Helium weighs 4 Atomic Mass Units (AMU).

Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
What is the mass number and how do you calculate it?
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
How do you calculate the atomic mass number?
the atomic mass number is the number of protons/electrons in an atom
How you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the number of neutron in the nucleus of an atom?
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
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.
How do you calculate nutrons?
neutron can be calculated by subtracting the atomic number of the particular atom from its mass number.
How do you calculate the mass of one Nitrogen atom?
The mass of a nitrogen atom is approximately 1.008 grams/mole, based on its atomic weight. To calculate the mass of one nitrogen atom, you would divide this value by Avogadro's number (6.022 x 10^23) to get the mass of one nitrogen atom, which is about 1.66 x 10^-23 grams.
Why do you calculate the number of electrons by the atomic mass and number?
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.
