1. Calculate: Concentration is measured by molarity (M), or moles per liter. Brackets are also used to symbolize molarity. For example, if 0.6 moles of HNO, are dissolved in a liter of water, you would say [HNO3] = 0.6 M. A. Because HNO, is a strong acid, it dissociates almost completely in water. That means the concentration of H" is very nearly equal to that of HNO,. What is [H*] if [HNO,] is 0.01 M?. B. The pH of a solution is equal to the negative log of H' concentration: pH = -log[H*] What is the pH of this solution? C. What is the pH of a 0.6 M HNO, solution?

Question
1. Calculate: Concentration is measured by molarity (M), or moles per liter. Brackets are also
used to symbolize molarity. For example, if 0.6 moles of HNO, are dissolved in a liter of
water, you would say [HNO:] = 0.6 M.
A. Because HNO, is a strong acid, it dissociates almost completely in water. That
means the concentration of H* is very nearly equal to that of HNO3.
What is (H') if [HNO] is 0.01 M?
B. The pH of a solution is equal to the negative log of H' concentration: pH = -log[H*]
What is the pH of this solution?
C. What is the pH of a 0.6 M HNO, solution?
