Answer: When you say "how much", and "lift" practically what you mean is "What VOLUME of He at atmospheric pressure will lift a given object using a conventional baloon-like contraption. Balloon is compressed at a constant temperature causing the volume to decrease to 0.025m^3. However, they need to be checked by the moderator before being published. We are now in a position to calculate how much helium we need! Furthermore, I also have noticed that because of the lower pressure higher in the atmosphere helium expands and balloon seems filled up. Helium weighs 0.1785 grams per liter. But it will still weigh 2lbs (+Ballon) No, I'm not confusing that. If an air mass started to rise then contract due to cooling, that would be the end of that convection event. A 12-liter balloon contains 0.52 moles of helium gas. So, this is an application of Avogadro's law (which is derived from the ideal gas law or PV = nRT where P is the gas pressure, V is the volume occupied by the gas, n is the moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin). What is the correct way to screw wall and ceiling drywalls? The difference is not as great as it is between water and air (a liter of water weighs about 1,000 grams, while a liter of air weighs about 1 gram), but it is significant. \end{align}. We can now simplify Equation \ref{1} greatly: \begin{align} Mass of balloon = 80 kg. After hydrogen, helium is the second most abundant element in the universe. Technically once we calculate the amount of helium in the balloon at sea level, we only need readings for temperature and pressure at the higher altitude, not density, as we saw in the second calculation which lead to $312\text m^3$. How is Jesus " " (Luke 1:32 NAS28) different from a prophet (, Luke 1:76 NAS28)? The radius of the balloon (when filled) is R = 5.3 m.
