What volume of 95% sulphuric acid (density=1.85g/cm3)and what mass of water must be taken to prepare 100cm3 of 15%solution of sulphuric acid (density=1.10g/cm3)?
Concentrated nitric acid used in laboratory work is 68% nitric acid by mass in aqueous solution. What should be the molarity of such a sample of the acid if the density of the solution is 1.504 g mLā1?
