    weight of air displaced - weight of balloon = lift

    We know gravity is ~10 meters a second per second downward. So, if I had an object of mass M the force needed to keep an object up in the air would be M*10. Now, the only question is how much force does one balloon produce in the upward direction?

    Edit: beaten
