The weight of a cubic meter of helium can be calculated by multiplying the density of helium (0.1785 kg/m^3 at 0 degrees Celsius and 1 atmosphere pressure) by the volume of one cubic meter. Therefore, the weight of a cubic meter of helium is approximately 0.1785 kilograms. Helium is a very lightweight gas and is commonly used in applications where buoyancy is important, such as in balloons and airships.
The short answer is 28.9 grams or 1.02 ounces.
But it depends on the temperature and pressure of the air, the helium, and possibly also what's holding the helium.
The upward force on the helium is called the buoyancy. The weight it can "pick up" is the buoyancy less the weight of the helium itself.
At sea level pressure, air has a density of 1.2 g/L at an 'normal' pressure.
Helium is of course less dense, at 0.1786 g/L.
1 (cubic foot) = 28.3168466 L
So the net buoyancy is (1.2 g/L - 0.1786 g/L) * 28.32 L = 28.9 g.
The helium's container matters because some containers are compressible. Eg a rubber balloon will expand as it rises or shrink as it falls. This can affect the buoyancy.
That would depend on the temperature and pressure - but if you assume STP of 273.15 K (0° Celsius) and 1 atm, 1 cubic meter of gas would contain 45.76 moles of Helium. At 4.002 g per mole, that would be 183.2 g or 0.1832 kg. Subject to earth's gravitational acceleration - which is 9.81 m/s², that would weigh 1.797 N.
The density of steel is 7850 KG/M3
400kg
That is approximately 5,300 pounds.
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 !
2000 to 2500 Kg/cubic meter depending upon the grade of concrete
The weight of standard air is 1.2256 Kg/ Cubic Meter The weight of hydrogen is 0.0857 Kg/ Cubic Meter The weight of helium is 0.1691 Kg/ Cubic Meter Subtracting the weight of hydrogen from air gives you the gross buoyant lift of hydrogen as 1.1399 Kg/Cubic Meter Subtracting the weight of helium from air gives you the gross buoyant lift of helium as 1.0565 Kg/Cubic Meter These values are variable under altitude, pressure, temperature, humidity and purity of gas. Hope this helps you.
At sea level approximately 1Kg
1 cubic meter helium lifts 1 Kg weight at sea level.
Litre or cubic meter for helium as a gas; litres for helium as a liquid.

A cubic meter of pure water has weight of 1000kg
You will need to know the weight of the plastering. If you identify a weight per cubic meter, multiply it by the number of cubic meters that you have.

33 Ton, On average granits weighs 2.75 Ton per cubic meter
The weight varies; but if it's dry sand, the cubic meter will weigh around 1500 kilos.
The weight of subsoil can vary depending on its composition. On average, the weight of subsoil can range from 1.5 to 2.2 tonnes per cubic meter.
