I expect that the answer that you are required to give is the mass. However, the mass of any radioactive object is very definitely not an unchanging measure. And even with non-radioactive materials, some Grand Unified Theories (GUTs) of matter suggests that protons themselves might decay with a half life of over ten decillion years! While that is hugely greater than the 14.5 years that the universe has been in existence, it is not unchanging - if true.
The measurement of how much matter is in an object is its mass. Mass is typically measured in units such as grams or kilograms.
It is the mass of the object.
The measurement of the amount of matter in an object is its mass. Mass is typically expressed in units such as kilograms or grams and represents the quantity of material in an object, irrespective of its volume or weight.
Density, refractive index, thermal conductivity, specific heat and many others.
Yes, mass is a measure of the amount of matter in an object. It is a fundamental property of an object and is typically measured in units like kilograms or grams.
