Icebergs consist of freshwater ice and float in the ocean with only about 10.2% of their volume above water (the "tip of the iceberg," so to speak). this percentage can vary, depending on the condition of the ice. assume that the ice has the density 0.92x10^3kg/m^3 , although, in reality, this can vary considerably, depending on the condition of the ice and the amount of impurities in it. part a what does this 10.2% tell us is the density of seawater? express your answer using four significant figures. part b what percentage of the icebergs' volume would be above water if they were floating in a large freshwater lake such as lake superior? express your answer using two significant figures.
