ANSWER
Nitric acid (HNO3) is a strong acid and so it is completely dissociates in water into H+ and NO3-. Nitric acid is fall under mineral acid category. Since HNO3 is a monoprotic strong acid, one mole of HNO3 gives one mole of H+ ions.
The molarity of HNO3 = 3.4 10-2. The molarity becomes the [H+] concentration of 3.410-2.
The formula to find the pH is -log[H+]
Therefore, pH = -log[3.410-2] = 1.468 = 1.5 (rounded value)
So, option (d) is correct.
