The pH of a solution is given by the formula pH = -log H+ , where H+ is the concentration of hydrogen ions in moles
per liter in the solution. Use this formula to solve the problem. Round answer to one decimal place if necessary.
Find the pH of a sample of lake water whose [H+] is 3.05 × 10^-9 moles per liter.
