2. You want to produce 70%(v/v) rubbing alcohol in the laboratory. You poured 20L of distillate having a 99% (v/v) concentration into a barrel. You open the valve such that the solution exits the barrel at 10mL/sec into another container which is empty. Simultaneously, you pour distilled water into the barrel at a flowrate of 30mL/sec. After achieving the desired concentration, what is the concentration in percent by volume of the alcohol in the second container?
