A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 69.32 g.L The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 5.02 g⋅L¯¹. Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Be sure your answer has the correct number of significant digits.
