Even though I think I'm in the right way, it doesn't accept my answer.
A 2.8 balloon is filled with helium ( density = 0.179 ).
If the balloon is a sphere with a radius of 5.4 , what is the maximum weight it can lift?
Express your answer using two significant figures.
I tried to solve it like this:
(Density of air)*(Volume of balloon)*(9.8) - Weight of the balloon - Weight of Helium gas. and I found 6600 N, however it doesn't accept it.
Where do I make the mistake?
