It varies, but it is several tons per cubic centimeter - i.e., millions of times as dense as water.
Dwarf stars, particularly white dwarfs, have extremely high densities, often exceeding 1 million grams per cubic centimeter. This is due to the collapse of the star's core after it has exhausted its nuclear fuel, leading to a compact structure primarily composed of electron-degenerate matter. In contrast, red dwarfs, which are low-mass stars still in the hydrogen-burning phase, have lower densities, typically around 15 to 30 grams per cubic centimeter. Overall, the density of dwarf stars can vary significantly based on their type and evolutionary stage.
Dwarf planets vary widely in mass; for example, Pluto has a mass of about 1.3 x 10^22 kilograms, while Ceres, the largest object in the asteroid belt, weighs around 9.1 x 10^20 kilograms. Other dwarf planets like Eris and Haumea have masses of approximately 1.7 x 10^22 kilograms and 4.0 x 10^21 kilograms, respectively. Their weights are determined by their size, composition, and density, leading to significant variations among them.
A neutron star has slightly more mass than a white dwarf. This results in higher gravitational attraction. As a result, in a white dwarf, the star's mass (roughly the mass of the Sun - may vary in different white dwarves) has a diameter of a few thousand kilometers, and a density of a few tonnes per cubic centimeter. The neutron star, on the other hand, has a diameter of only 20-30 kilometers, and a density of millions of tonnes per cubic centimeter. For comparison, water has a density of 1 gram per cubic centimeter, other substances around us have similar densities; so the density of a white dwarf is millions of times the density of water, while a neutron star has billions of times the density of water.
White dwarves have run out of fuel; therefore they have stopped producing energy, through nuclear fusion. Also, they are very small - smaller than planet Earth, while (for comparison) our Sun has 109 times the diameter of Earth; they are very dense (a cubic centimeter of white dwarf matter has a mass of several tons), and fairly hot - though, since they don't produce energy, they will gradually cool down.
It varies, but it is several tons per cubic centimeter - i.e., millions of times as dense as water.
A typical white dwarf has an exceptionally high density, often exceeding 1 million grams per cubic centimeter. To put this in perspective, a white dwarf's mass is comparable to that of the Sun, but it is compressed into a volume similar to that of Earth. This extreme density results from the collapse of a star's core after it has exhausted its nuclear fuel, causing electrons to degenerate and support the star against further collapse.

A teaspoon (5ml) of white dwarf material would weigh about 6,500,000 grams or just over 7 metric tons.
So far most dwarf planets are found in a ring of icy debris beyond the orbit of Neptune known as the "Kuiper Belt." Only one dwarf planet is recognized in the belt of dry material between Mars and Jupiter known as the asteroids. That dwarf is called Ceres.
A nova event occurs when a white dwarf in a binary system accepts material from a nearby companion star, causing a runaway nuclear fusion explosion on the surface of the white dwarf. This explosion results in a sudden increase in brightness that can last for several days to a few weeks.
A teaspoonful of white dwarf material on Earth would weigh millions of tons due to its incredibly dense nature. White dwarfs have masses comparable to the Sun but are compressed into a volume roughly the size of Earth, resulting in an immense weight for even a small amount of material.
