A sample of concentrated nitric acid has a density of 1.41 g/mL and contains 70.0%HNO; by mass. What mass of HNO3 is present per liter of solution?
TReferencer A solution is prepared by adding 49.9 ml concentrated hydrochloric acid and 19.7 ml concentrated nitric acid to 300 ml water More water is added until the final volume is 1.00 L. Calculate H".COH)and the pH for this solution. (Hint: Concentrated HCl is 38% HCI (by mass) and has a density of 1.19 g ml., concentrated HNO, is 70% HNO, (by mass) and has a density of 1.42 g/mL.] OH")= M pH-

20 A nitric acid solution containing 71.0% HNO3 (by mass) has a density of 1.42 g/mL. ow many moles of HNO, are present in 2.36 L of this solution? b) Determine the molarity of the acid.
What is the molarity of concentrated nitric acid that is 70.4 wt%?
Solve the following 1) A solution is made by adding 24.8 mL of concentrated nitric acid (70.4 wt%, density 1.42 g/mL) to some water in a volumetric flask, and then adding water to the mark to make exactly 200 mL of solution. Calculate the concentration of this solution in molarity. 2) A 72.0 mL aliquot of a 1.50 M solution is diluted to a total volume of 288 mL. A 144 mL portion of that solution is diluted by adding...
