A geologist removes a sample of water from a lake in Nevada where the water level has been slowly dropping over time. The sample is found to be 0.02M in borax. The lake is circular in shape and is currently 500 meters in diameter and 50 meters deep. Using the given data predict the level of the lake when borax will begin to precipitate on the shore if the mean temperature of the lake water is 15degC. Assume that the lake is equally deep at all points.
