mass number= protons+nutrons
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 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.
the atomic mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
The number of protons and neutrons in the nucleus
1 / mass of a proton = avogadro's number 1 / mass of a proton = avogadro's number
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
Hydrogen is a non metal element. Mass number of it is 1.
You subtract 54 from the mass number.
Atomic mass - Atomic number
To calculate the mass of a cell, you would need to know the density of the cell and its volume. The mass can then be calculated by multiplying the density by the volume. Mathematically, Mass = Density x Volume.
