A scientist has a beaker containing 20 mL of a solution containing 20% acid. To dilute the acid, she adds pure water. An equation for the concentration in the beaker after adding n mL of water, C(n) , is 8 C(n) 11 + n a. Find the new concentration (of acid) if 7 mL of water has been added. The new acid concentration will be at %. b. What is the behavior as n → ∞ , and what is the physical significance of this? As n → ∞ , C(n) → Your explanation for the physical meaning:
