The thickness of subfloor needed generally depends on how far apart your floor joists are located. In most cases, floor joists are 16" center-to-center and the most common thickness of subfloor is 3/4". Some homes will have 1/2". If your floor joists are farther apart, you will need correspondingly thicker subfloor to adequately support weight between the wider joists. Your city's building codes department will be able to specify what you need (some cities may have differing requirements).
Another factor might be the kind of flooring you will install. For carpet, vinyl, laminate, wood and other non-rigid flooring types, the 1/2" or 3/4" will be adequate. For tile, the Tile Institute of America recommends no less than 3/4" subfloor on 16" centers floor joists - but with 1/4" backerboard installed on top of subfloor. See their website or contact your city codes department for specifics on a different span of joists.

How do you calculate floor mass of concrete screed floor?
The bulk density of screed is 22KN/m³. Simply multiply by the thickness to get a weight. 22kN/m³ = 22000N/m³ 1 Newton = Mass x Acceleration = kg * g (g is acceleration due to gravity) On earth g is 9.8 22000N/m³ = 2245kg/m³ You then multiply this by the thickness to get the surface mass. Say it is 50mm 2245kg/m³ x 0.005m = 112.25kg/m² You then multiply this by the area of the floor to get the total floor weight. If you have 100m² floor area then 112.25kg/m² x 100m² = 11225kg
