A cubic metre (or 'stere' as it is correctly known ) is 35.1 cubic feet. -In wet asphalt concrete that weighs about 5,250 pounds - just over 2 and a half tons !
The weight can only be determined if the exact weight of the reinforcement, as well as the exact displacement of the reinforcing is known. Thus the weight should be 1 sq meter x thickness of the concrete minus the exact displacement of the reinforcing, plus the weight of the reinforcing. The weight per cubic meter of concrete is 2450 kg.

Concrete is sold in cubic (volume) measurements not square (area) measurements.
to answer your question, one must know the thickness of the slab? then only the weight can be calculated
I'll make the assumption that 150 is meant to be metres. 150x6 is 900, x 2.5 is 2250

At least 3 cubic yards for a 4-inch slab. You'll need 4.75 cubic yards for a 6-inch slab.
1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.
About 2.11 Cubic Yards.
1 kg of any material weighs the same as 1 kg of any other material. With normal Earth gravity, a mass of 1 kg has a weight of about 9.8 N.
Concrete averages in weight between 90lbs per cubic foot to 140lbs per cubic foot. Knowing that its a simple equation. L x W x H = C x W. in this case 800 cubic feet. So basically the slab can weight between 72,000lbs and 112,000lbs. Length x Width x Height = Total Cubic Feet x Weight per cubic foot = Total Weight
