How do a stars radius compare with their mass?
the bigger the radius the more the 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.
Does smaller mass stars have a greater luminosity than larger mass stars?
This is not necessarily true. most of the time stars with a larger diameter have more mass but some stars with a smaller diameter are more dense and have a greater mass. Find a main sequence star chart and you can compare the data.
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
How do the properties of long-lived stars compare to those of short-lived stars?
Long-lived stars begin their lives with less mass and a smaller amount of hydrogen fuel. and Long-lived stars are less luminous during their main-sequence lives.

How do the numbers of low-mass stars compare with those of higher-mass stars in new star clusters?
In a newly formed star cluster stars with low masses must greaty out number stars with high masses. High mass stars are rare and low mass stars are extremely common.
How do the lengths of two radii of the same circle compare?
The sum of two radii of a circle is the same as the diameter of the circle.
Does smaller mass stars have a greater luminosity than larger mass stars?
This is not necessarily true. most of the time stars with a larger diameter have more mass but some stars with a smaller diameter are more dense and have a greater mass. Find a main sequence star chart and you can compare the data.
How does bromine's atomic radius compare to chlorine's?
Bromine's atomic radii is larger than that of chlorine.
What is the difference between a giant and a supergiant star?
Typically,giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun.Whereas Supergiants have a radii between 30 and 1,000 solar radii and luminosities between 30,000 and 100,000 times that of the Sun
If your mass on earth is m your mass at a distance of 3 earth radii from the center of the earth will be while your weight will be?
-- If your mass is 'm', then your mass is 'm', regardless of whether you're on the earth,2 earth radii out in space, or on the moon. Mass doesn't change.-- On the surface, your distance from the center of the earth is 1 earth radius. Weight isinversely proportional to the square of the distance from the center of the earth, so at adistance of 3 earth radii from the center, your weight is 1/32 = 1/9th of your weight on thesurface. If your mass is 'm' then your weight on the surface is mg = 9.8m newtons, and at3 earth radii from the center it's 1.089m newtons (rounded).

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).
What is a mass of stars called?
An isolated and distinct mass of stars is a galaxy.
