Inflating a Weather Balloon – High Altitude Science

Helpers - Inflating a weather balloon on your own is very challenging, even if you're experienced. Safety First It is very important that your inflation system has a built in gas regulator and only uses high pressure hose. Helium gas cylinders are pressurized between 1,800 and 2,000 PSI. Working with such high pressure gas can cause serious injury.

36.39 -- Helium-filled balloon - UCSB Physics

Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l. Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g. Of course, this would include the mass of the balloon skin itself, and we are assuming that the pressure inside the balloon is not significantly greater than the surrounding pressure of 1 atm.
