A chemical reaction's concentration, in moles per liter, is modeled by the function , where represents the number of purification steps completed. Which of the following statements is the best interpretation of the model?
The initial concentration of the chemical is 95 moles per liter.
For each purification step, the concentration of the chemical decreases by 5%.
For each purification step, the concentration of the chemical decreases by 95%.
After 5 purification steps, the concentration of the chemical will be 800 moles per liter.
