Suppose that during a certain step in a chemical manufacturing process the amount of chlorine dissolved in a solution, measured in parts per million (ppm), is related to the elapsed time measured from the beginning of the step. Use the following table as a representation of this relationship. What does the ordered pair (6, 20.4) mean in the context of this situation?
In the given context, the ordered pair (6, 20.4) means that after 6 units of elapsed time in the chemical manufacturing process, the amount of chlorine dissolved in the solution is measured to be 20.4 parts per million (ppm).
