Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: х10 Answer-1 A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 9.0 g·L The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 5.3 g·L *. 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.
