14. Concentrated nitric acid (HNO3, mw = 63 g / mol) is actually an aqueous solution containing 70.3 mass percent HNO3. The solution density is 1.43 g / mL. What is the molarity of this solution ? [10 pts] molarity of HNO3 = mol HNO3 / 1 L soln = (1.43 g soln/mL)(70.3 g HNO3/100 g soln) / (63 g HNO3/mol HNO3)(0.001 L/mL) = 16.0 M. 15.
