Q. The mass and volume of a natural soil sample are 2.1 kg and 1×10-3 m3, respectively. When fully dried, the mass of the soil sample becomes 2 kg without any change in volume. Assuming the specific gravity of soil particles to be 2.5, and water density of 1000 kg/m3, the degree of saturation of the natural soil sample is______________%.
