Using mean size values and knowing the volume of the dispersion measured, is it possible to calculate the actual/approximate number of particles present in a sample?

'The error is higher if the polydispersity is high.'
In other words if it is not very close to monodispersity the result will be very far from a good guess because a very large number of small particles contribute to a small change in volume of the particles but contribution to scattering intensity is minor.
