A white dwarf's mass is comparable to that of the Sun while its volume is comparable to that of the Earth.
The Sun is 100 times larger than the Earth, so a white dwarf has a mass 100 times greater than the Earth.
The limit is the Chandrasekhar limit [See related questions] of 1.38 -> 1.4 solar masses.
A typical white dwarf will have about 1 solar mass compressed into the size of the Earth.
Since we cannot ever set foot on a star without combusting, this question is pretty much inanswerable.
It is true that a white dwarf above about 1.4 solar masses cannot exist. When a star dies, most of the mass does not become part of the remnant. A star 5 times the mass of the sun will shed most of its mass during the red giant phase. Only the innermost portion will collapse to form a white dwarf.
No. It does not have enough mass. Only stars 8 times the mass of the sun or greater can become pulsars. The sun will become a white dwarf.
White dwarf
The white dwarf (which is made mostly of carbon) suddenly detonates carbon fusion and this creates a white dwarf supernova explosion.
Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.

A white dwarf is the remnant of a low to medium mass star.
Several times smaller than our Sun. Details vary, depending on the type of dwarf star (a red dwarf and a white dwarf are quite different things), and the exact mass.
No. A white dwarf is the remnant of a low to medium mass star.
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
A white dwarf, also called a degenerate 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.
Not necessarily. A white dwarf is simply the remains of a low to medium mass star that has died. A red dwarf is a low mass star. Since red dwarfs last longer than medium mass stars, one could easily be older than a white dwarf.
A white dwarf could be smaller or bigger than the moon since it's size varies depending on the mass of the white dwarf. Since the mass of the moon is 7.347 x 1022 kg and the mass of Pluto is 1.31×1022 kg the size of a white dwarf is also smaller or bigger than Pluto depending on it's mass.
white dwarf
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.
No. It does not have enough mass. Only stars 8 times the mass of the sun or greater can become pulsars. The sun will become a white dwarf.
