The volume of a 8inx8inx16in block is 1024in^3 or .59259ft^3. I would assume that steel is used for the reinforcing. The density of steel varies from 484 to 503 lb/ft^3 and the density of concrete varies from 109.25 to 149.83 lb/ft^3. So assuming that the steel reinforcement accounts for 6% of the volume then the weight of the steel would be greater than 17.21lbs (.59259ft^3*0.06*484lb/ft^3) and less than 17.88lbs (.59259ft^3*0.06*503lb/ft^3). The concrete would then account for 94% of the volume and its weight would be greater than 60.86lbs (.59259ft^3*0.94*109.25lb/ft^3) and less than 83.46lbs (.59259ft^3*0.94*149.83lb/ft^3). So with all of these assumptions the block would weigh between 78.07 and 101.34lbs.

Depends on which size block and type. A 8x8x16 (common size) thick blocks with heavy gravel mix and small 3 ports can average around 56 lbs. or as light as 28 pounds if hollow with lightweight mix. There are usually 108 8x8x16 blocks on a pallet. This gives you an approximate weight between 1.5-3 tons. That is between 3,000 and 6,000 pounds.
