Cassiopeia absolute magnitude is 2.20 to 2.23
Its absolute magnitude is -7.92
The magnitude of Cassiopeia A, a supernova remnant, varies depending on the wavelength observed. In visible light, its magnitude is around 12.2, making it too faint to be seen with the naked eye. At radio wavelengths, it is much brighter due to synchrotron radiation emitted by high-energy electrons.
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
The absolute magnitude is -7.92
Betelgeuse has an apparent magnitude of 0.58 and on absolute magnitude of -6.05.

The magnitude of the Schedar star in Cassiopeia is -1.985. Remember Negative stars are brighter.
Cassiopeia A is a supernova remnant in the constellation Cassiopeia.It has no single point of luminosity, so no definitive magnitude can be attributed to it.
An estimation of the absolute magnitude is −20.9. See related question.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
Constellations don't have an absolute magnitude. That is a property of individual stars.
