Each mole has a volume of 22.4 liters and a mass of 28.97g/mol at STP, therefore a cubic meter of air is 1.293 kg at 0o Celsius on the coast. An average mass of 1.2kg per m3 at room temperature and standard pressure is often used as a rule of thumb.

### How much hydrogen is enough to lift up 1 kg weight from the ground?

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.
