A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 43.33 g L.. The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 3.1 g.1.¹. 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.
