It takes about 10 million years for it to form. This is not necessarily true for all nebulae. It is hard to tell the exact average of how long it takes. There are different factors that determine how long it takes.
light years
Becuase nebulae tell us how stars get formed so the composition, density and size of a nebulae cloud says a lot about its age, likelihood of stars forming and the type of stars that might form.
emission nebulae and reflection nebulae.
In astronomy, diffuse nebulae is the general term for illuminated nebulae. The three types of diffuse nebulae are reflection nebulae, emission nebulae and supernova remnants. They are diffuse as opposed to the non-diffuse dark nebulae, i.e. the particles have spread out.
No, they are ionized gases thrown off stars near the end of their fusion cycles. They are expanding clouds of matter, quite different from the nebulae in which stars form.
it depends on how large the nebulae is. The largest of nebulae (in both distance and height) form the largest number of stars while the smallest of nebulae (in both distance and height) form the least number of stars. Therefore there is no fixed number for the number of stars that can be formed from a single nebulae (a variable amount of stars can be formed from one nebulae)
Stars form in a nebulae
Most stars came from Nebulae.

Most of the nebulae that exist now are formed from the expelled remnants of dead stars. The gas that made up the original nebulae form with the Big Bang.
