That is an oddly phrased question.
If you're looking for the mass to luminosity relationship, it's generally L = M^3.5.
But your question asks for the mass to light ratio. I'm not sure what the "light" part is referring to. But as you are given the luminosity, and the mass, perhaps you mean the ratio between those two quantities? Then you just do some division to create a ratio...
White dwarfs.
sneezy was dwarf in the movie snow white he is a dwarf that always used to sneeze that is why his name is sneezy :)
White Dwarf, Sun, Red Giant, Supernova
It is a white dwarf.
A white dwarf who's progenitor star was about the same mass as our Sun will leave behind a stellar remnant around the size of our Earth. Obviously if the progenitor star was larger or smaller, then the stellar remnant will also be larger or smaller.
The luminosity of a white dwarf depends entirely on it's age. The older it is, the less luminous it is.

Luminosity will also depend on the surface area. The Sun has about 10,000 times the surface area of a typical white dwarf.
No. Stars of different sizes and composition have different luminosity (light) levels. A very big star will most likely be blue and shines very brightly, while small stars like white dwarf stars emit very white light, but are mostly very dim.
even though a white dwarf may burn hot, it's size is what limits it's luminosity. Here is one way to look at it: Imagine a white dwarf with the mass of our sun. Our sun's surface temp is right around 5,770K and weighs one solar mass. Now, this imaginary white dwarf would be about the size of the earth and have a surface temp of around 10,000K - 11,000K. This white dwarf would have a surface area 1/333,000 of the sun. A white dwarf of this size is about average and as you can imagine, has very little room to put out energy compared to other solar masses.
That can either be an old white dwarf, a red dwarf. or a brown dwarf.
The plural of dwarf is "dwarves". White dwarves are hotter than supergiants. White dwarves also have much less luminosity. This is related to their very small surface area. Since white dwarves no longer produce energy, they will cool down over time - but this takes quite a while.
