How many stars are there in a Globular Cluster of 10^5 solar masses? I was wondering whether there is an easy way to approximate the number of stars in a Globular Cluster (GC) with 10^5 solar masses. 

Can one, for instance just assume the GC is made of sun-like stars and therefore has 10^5 stars? 
Or is this too simple? 

Thank you for your answers!
The mean mass of the initial mass function is ~0.3 solar masses (Maschberger 2013).  A GC with 10^5 solar masses will therefore have ~3 x 10^5 stars in it.  Since the most massive stars will already have died in a GC, the mean mass of the present-day mass distribution of the GC will actually be slightly lower, implying a slightly larger number of stars, but this will be a relatively small correction (certainly not more than a factor of 3).
