32Q). Concentrated nitric acid used in the laboratory work is 68% nitric acid by mass in aquous solution. What should be the molarity of such a sample of the acid if the density of the solution is 1.504 g/m2. (3Marks) Ans: density =1.504 g/m2. 68% means 68g in 100g solution. Volume of solution =100g/1.504g/m2. Wt of Nitric acid …
