I have a couple of questions on archimedes' principle

  1. Feb 17, 2009 #1
    the question is:
    consider that a balloon filled with 1 liter of water (1000 cm^3) in equilibrium in a container of water,
    what is the mass of the liter of water?
    what is the weight of the 1 liter of water?
    what is the weight of water displaced by the balloon ?
    what is the bouyant force on the balloon?

    Are there any equations i can use for these four questions. i really dont understand how to do this without any equations...

    Thank you!

    Welcome to PF.

    There is w = m*g

    Then there's Archimedes' principle.

    So how much water is displaced by 1 liter of water?

    Thank you. so here is what i came up with...
    a. 1000 g
    b. 9,800 N
    c. 9,800 N
    d. 9,800 N

    Any make sense?
