Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
No, subscripts in a chemical formula represent the number of atoms of each element in the compound. The relative mass of each atom is accounted for by the atomic mass of the element found in the periodic table. So, atomic mass, not subscripts, gives you the relative mass of each type of atom in a compound.
The atomic mass of an atom represents the average mass of an atom of that element, taking into account the relative abundances of its isotopes. It is measured in atomic mass units (amu) and is usually found on the periodic table below the element's symbol.
The mass number in helium represents the total number of protons and neutrons in the nucleus of a helium atom. It is used to determine the mass of the atom and differentiate between different isotopes of helium.
The superscript (40) represents the mass number, which is the total number of protons and neutrons in the nucleus of the atom. The subscript (19) represents the atomic number, which is the number of protons in the nucleus of the atom. Therefore, in the notation 40 K represent 19, the atom is potassium with a mass number of 40 and an atomic number of 19.
The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

The atomic number.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
An atom of an element does not represent the actual mass of its atom because the atomic mass listed on the periodic table is an average mass calculated based on the relative abundance of different isotopes of the element. Isotopes are atoms of the same element with differing numbers of neutrons, so the actual mass of an atom of a specific isotope may vary slightly from the average atomic mass.

You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
