It depends on the density, how much moisture, how much fibre etc.

It depends if it is wet or dry.
depends on the soil structure and composition, probably around 600-800 Kg
On one site I found the weight of one cubic yard of topsoil listed as 1,35 US tons
This question has no real answer as it depends where you stay and the availability of top soil. How much is a cubic yard of topsoil in Iceland? How much is a cubic yard of topsoil in the Sahara Desert? How much is a cubic yard of topsoil in Washington DC? etc. etc. Check a local newspaper or nursery/ garden centre

Topsoil is NEVER sold by the "truck-load". Usually in yards or tons, as there are several differant sizes of trucks... A "yard" of dry topsoil should weigh a little less than 1 ton.
about 2700 pounds per cubic yard
It depends on what it consists of. It could vary greatly.

A cubic yard of topsoil, if compacted to get the air pockets out will weigh more than 1 tone. If the topsoil is loose, a cubic yard of it could weigh about 1 ton. A lot depends on the topsoil, and whether it has more stone dust or less in it. The more moist the topsoil is, the more likely it will weigh more than a ton.
This will depend on what is under the topsoil.
The weight of a yard (a cubic yard, more accurately) of topsoil varies greatly depending upon its moisture content and how well packed it is. But figure 2000 to 2400 pounds.
