1. A plant currently manufactures 100,000 liters of normal saline solution (9 grams of NaCl/1000 ml of water) each day for use in intravenous fluid delivery. The CEO of the company wants to diversify and make hypertonic saline solution (70 grams of NaCl/1000 ml of water) for use in cough expectorates.
a. If the CEO wants to turn 100,000 liters of normal saline solution into hypertonic saline solution, how many extra kilograms of NaCl need to be added?
b. If the CEO does not want to change the amount of salt per day and wants to split the salt input evenly between the two solution types, how many liters of each solution would the company be able to make each day?
