Homework Help: Maximum weight that helium balloon can lift

  1. Dec 12, 2005 #1
    Hi. I have been trying to do this question for about an hour now...

    A 0.12 kg balloon is filled with helium (density-0.179). If the ballon is a sphere with a radius of 5.2m what is the maximum weight it can lift.

    I tried using the P=M/V then Fb=pgV...No luck...Help..
