The number of juvenile spiders in an egg sck varies greatly from species to species. There may be a few (less than a dozen) for very large spiders or several hundred for some other kinds of spiders.
there is around ten thousand to one hundred thousand spiders in the egg sac depending on the size of the spider
there can be up to 600 eggs
around 3000 i believe...
that depends on what type of spider it could be from 100 up to 900
hundreds of eggs round about!
