A definition of mass, as found in Google:

"Mass is a measurement of the amount of matter or substance in an

It's the total amount of protons, neutrons, and electrons in an object."

 More or less as per my school books of seventy yeass ago.

The definition from above is wrong, because mass is NOT a measure for the number of protons or similar.
Mass is a measure for resistance to acceleration.
The 'amount of matter' is not measured in kg but in mol.
