A company, at the end of its production process, generates 3000 liters of copper solution with a concentration of 0.005 mol L–1 as waste per month. Based on this information, select the correct alternative regarding the waste. a) It can be disposed of without treatment, as it has a concentration below the legal limit. b) Its concentration is 0.005 g L–1. c) It cannot be disposed of, as it has a concentration higher than the limit established by law. d) 1.5 kg of copper are found in its total volume. e) Its concentration is 1 mg L–1, which is equivalent to a concentration of 0.001 mol L–1.
