There has to be something given.
Thats what I was thinking, let me see if i missed something
Oops! I forgot that it was a 2 part question.
Part 1:
Calculate the bouyant force on a 2.00 L helium balloon.
Volume:2.00 L
Helium's density: 0.18x10^-3
FB=density*gravity*volume=> 3.53x10-3 N

other then these numbers nothing else was given for part 2(the part i need help in).
