Despite having a radius similar to Earth's, what mass do White Dwarfs retain?

Nearly the entire mass of the original star (about the mass of the Sun)

White dwarfs are extremely dense stellar remnants; they are small because they are the collapsed core, but they retain almost all the mass of the star they originated from, such as the Sun.
