Some scientists estimate that the oceans contain as much as 50 quadrillion tons (50,000,000,000,000,000) of dissolved solids. If the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 166 m (500 feet) thick, about the height of a 40-story office building.
