There really isn't any specific number. A warm engine in good condition with light load at sea level will usually make about 20" of vacuum. The engine being worn or cold, loads like A/C or a lot of electrics, and higher altitude will all make the number lower.

If you need to know really accurately, the best you can do is hook a vacuum gauge to your engine and see what it reads.
