While 1 kg of water and 1 kg of sand have the same mass, the sand takes up less volume, making it denser and therefore heavier. Wet sand weighs less than dry sand because of the water filling the gaps between the particles. When it comes to a mixture of sand and water, the sand will sink to the bottom due to its greater weight.
