Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.

What is the typical size of the typical white dwarf in solar radii?
Average is about .01 Solar Radii. Oddly enough, the higher the mass of the White Dwarf, the smaller the radius
Is white drawf bigger than a nertron star?
Simply, neutron star is a big nuclear - of 10km radius and solar mass (mass density about  1017- 1018 kg/m3). The material in a white dwarf is supported by electron degeneracy pressure. The physics of degeneracy yields a maximum mass for a non-rotating white dwarf, the Chandrasekhar limit-approximately 1.4 solar masses-beyond which it cannot be supported by electron degeneracy pressure. The density of white dwarf is - 109 kg/m3. So its radius is much bigger 10km, but the mass can be less, as well as bigger of solar mass.
How can solar radii be used to describe the sizes of star including the subgroups of white dwarf giants and supergiants?
A star's radius is the distance from it centre to its visible surface. The bigger the star, the larger the radius. The radius is not the best means of comparing stars, it is perhaps better to compare stars by their mass.
A main sequence star of less than 8 solar masses ends its life as a?
A white dwarf.
What happens if the mass of a white dwarf reaches the 1.4 solar mass limit?
The white dwarf (which is made mostly of carbon) suddenly detonates carbon fusion and this creates a white dwarf supernova explosion.

Average is about .01 Solar Radii. Oddly enough, the higher the mass of the White Dwarf, the smaller the radius
Which of these has the smallest radius a 1.2 solar mass white dwarf a 0.6 solar mass white dwarf or Jupiter?
Jupiter is far larger than the other two. White dwarfs can be treated as Fermi gasses, and have the interesting property that as their mass increases their radius decreases. So the smallest is actually the 1.2 solar mass white dwarf.
Which of these objects has the largest radius 1. a 1.2 solar mass white dwarf 2. a 1.5 solar mass neutron star 3. a 3 solar mass blackhole?

As a white dwarf cools its radius will not change because?
The radius will not change because a white dwarf is made of electron degenerate matter, so temperature does not affect pressure or volume.
Is the moon smaller than a 1 solar mass white dwarf?
Yes. The white dwarf would be a bit bigger than the Earth.

How does a 1.2-solar-mass white dwarf compare to a 1.0 -solar-mass white dwarf?
The sun is still converting hydrogen into helium and on up the periodic table. Basically the sun is in static equillibrium between expansion and contraction due to gravity. When a sun reaches the white dward stage it no longer has the gravitational force to undergo the fusion of hydrogen into helium ect
What is the density of 1 solar mass white dwarf that has a radius of 10.10.10.10 km?
Re the radius, what units are the 10.4 in.(A white dwarf is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth).The density of matter in a white dwarf is, very roughly, 1,000,000 times greater than the average density of the Sun, or approximately 106 grams (1 tonne) per cubic centimeter.There is a limiting mass that no white dwarf can exceed called the Chandrasekhar limit, beyond which electron degeneracy pressure cannot support the object against collapse at which point it turns into a Type 1a supernova.
How Big Are White Dwarf Stars exact number in kilometres?
The universe is a much more complicated place than you seem to believe.The radius of a white dwarf star (I assume you mean a degenerate dwarf, not a main sequence star that happens to be white, which could also be called a "white dwarf") depends on its mass. An interesting property is that higher-mass stars have smallerradii.While we can't provide "an exact number in kilometers" (or any other unit), we can say that the majority of white dwarfs have radii between 0.008 and 0.02 solar radii (5600 to 14000 kilometers).
