Mass number in chemistry is the number of nucleons in the nucleus. Nucleon is the common name for proton and neutron. In case of Sodium atom the mass number is 23. If it gets changed by adding one more neutron then it is an isotope which is used in medical field as a radio isotope to study about the blood flow.

A hole, by definition, has nothing in it and so its mass is zero.
The definition of density is: Density = (Mass) divided by (Volume).A simple algebraic operation rearranges this definition to give: Mass = (Density) times (Volume)
Yes, Mass remains constant because the definition of mass does not mean weight. Mass means the amount of room and object takes.

The scientific definition of chemistry revision is when older chemistry theory is updated to reflect the current theory of chemistry. It is when a scientific formula has to be updated because new information has been found out.
The definition of chemistry easy is the study of elements, laws of combination and behavior. The definition of simple is having only one thing or element to do.
the application of the theories and principles of chemistry to practical purposes.

This is no chemistry but maybe a mis-spelling of 'H2SO4', in that case rephrase your question.
Any multiple of 6
Conservation of mass
Reduction means electrons are added.
