This is the classic problem of Archimedes when his king asked him to determine if his crown was truly made of gold. See: http://en.wikipedia.org/wiki/Buoyancy
The answer is the weight in water is equal to its weight out of the water minus the weight of the amount of water displaced. You have to know the weight of the displaced water which is simply the number of liters times its density, 1 kg per liter.
