Bouyant force was described by Archimedes to be equal to the force due to gravity of the substance displaced by the object. So in the case of a balloon in water the bouyant force is equal to the force of weight of the water that the balloon displaces otherwise known as the (volume of the balloon)*(density of water)*gravity.
Hope that helps

Why do steal boats float?
Its called bouyancy...any object that is sealed off against water is bouyant...because air is light that water and as long as that air is trapped inside and not let to escape it will float
How long can pumice float?
Forever. As long as the rock chambers holding the air don't break, there is no reason for it to sink. If the piece is too small and is depending on air in the outer edges to hold it up, once the air goes out of them, it might lose its bouyancy.
