10% v/v is 10 mL/100 mL soln but I think 10% HNO3 means 10g HNO3/100 mL solution unless you want 10% HNO3 mass percent which is 10 g HNO3/100 g solution. To any of these, however, you must know the concn of the HNO3 you're starting with.

density 1.42 g/mL. Then 1000 mL has a mass of 1.42 g/mL x 1000 = 1420 grams That is 70% HNO3 so g HNO3 is 1420 x 0.70 = about 994 g. The rest of it is water. g H2O = 1420-994 = about 426 g = 0.426 kg. mol HNO3 = 994/molar mass HNO3. m = mols HNO3/kg solvent.

pH = -log(HNO3) -1.39 = log(HNO3) I found HNO3 approximately 0.05 but you need to do it more accurately. Then mol HNO3 = M x L = ? mols HCl = M x L total mols H^+ = mols HCl + mols HNO3. volume = 145 mL + 493 mL = ? M new solution = total mols/total liters. Then pH = -log(H^+)

This is hardly organic chemistry. (HNO3) = 1.25E-3M. Since HNO3 is a strong acid (100% ionized), that means (HNO3) = (H^+); therefore, (H^+) = 1.25E-3 and pH = -log(H^+) = -log(1.25E-3) = ?? The answer is approximately 3
