Web1 apr. 2024 · Therefore hydrogen is the lightest gas. Density= mass Volume or Density ∝ mass (when volume =constant) Hydrogen is so light because its molar mass is only 2 g mo l -1 and a fixed amount of gas occupies a fixed volume regardless of the species of the gas. Hydrogen is the lightest element. Thus, the helium is not the lightest gas. jason records bribieThe gaseous state of water is lighter than air (density 0.804 g/L at STP, average molecular mass 18.015 g/mol) due to water's low molar mass when compared with typical atmospheric gases such as nitrogen gas (N2). It is non-flammable and much cheaper than helium. The concept of using steam for lifting is therefore already 200 years old. The biggest challenge has always been to make a material that can resist it.
