Google Content

it would make sense to brake this content in multiple pages, especially for SEO purpose.

I think there is no limit but you dont write a book without chapters.

Split your sites in topics, make keyword research and figure out the best brakes.

Agree with mj, As long as the content is interesting and informative its ok. Just create a category depending on the topic of your content.

Example:
If you write about cars you will not write one site full with used cars, new cars, car types, tuning, tires and so on but you write an informative, general article about cars and split up to these topics e.g. car type which you split up again to Audi, BMW, Ford, Porsche ...

Quality as well as Quantity both are important for contents writing.

Sitepoint ran an experiment last year to see how much content in a page would be indexed by the main search engines:

Just insert which is related to your business or service and which your customer could expect in their interest, I think you should not write much but it should cover basic information if your business and mj has give a good example in his second post so try to follow those pattern. Don't insert unnecessary content not the keyword stuffing.

as i suppose, there is no limit.... bt don't forget that, the size of that webpage should not cross the 30k-50 limit...
