mass number= protons+nutrons
the mass number of an atom is used to calculate the number of neutrons and protons in the nucleus of an atom
To calculate the mass of the cell you will need to know the mass and atomic number of the element. Multiply the number of atoms by the amount of grams per mole to get the mass.
the atomic mass number is the number of protons/electrons in an atom
Protons
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
grams and to calculate use a pan balance
1 / mass of a proton = avogadro's number 1 / mass of a proton = avogadro's number
The number of protons and neutrons in the nucleus
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.
