Hello, I have received your answer, thank you very much! I have one more question about helium, do I need to add this in the mass, if not why? Please kindly help me here, thanks a lot! Consider a child's balloon inflated with helium, the density of which is PHe = 0.18 kg/m3. The balloon envelope and the string have a total mass of 10g. What must be the diameter of the spherical balloon so that it floats motionless in the air of density p air = 1.27kg/m3? (Answer is 26cm)
