Answer

1.36 Explanation 1. Identify the nature of HNO_3 HNO_3 is a strong acid, which dissociates completely in water. 2. Calculate the concentration of H^+ Since HNO_3 dissociates completely, the concentration of H^+ ions is equal to the concentration of HNO_3, which is 0.044 M. 3. Calculate the pH Use the formula **pH = -\log[H^+]**. Substitute [H^+] = 0.044 M into the formula. pH = -\log(0.044)
