Suppose I knew the densities of air and helium and I make a helium balloon. If I know the lift (in Newtons), how can I find the volume of the balloon?

SUMMARY
This discussion focuses on calculating the volume of a helium balloon using Archimedes' law. To determine the volume, one must apply the formula: Volume = Lift / (g * (density of air - density of helium)), where 'g' represents gravitational acceleration. The participants emphasize the importance of accurately measuring the densities of air and helium to ensure precise calculations. Misapplication of the formula can lead to significantly inflated volume estimates.
