Well it depend on how much traffic do you have and the kind of traffic.
As start you could put a standard configuration:

<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>

<IfModule mpm_worker_module>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>

On some of my servers (a lot of small and fast answer) i've maxclients set to 500 (but i've also 8GB ram).

Try that and keep your apache monitored
