Concentrated nitric acid used in laboratory work is 68% nitric acid by mass in an aqueous solution. This means that 68 g of nitric acid is dissolved in 100 g of the solution. Molar mass of nitric acid (HNO(3)) = 1xx1+1xx14+3xx16 = 63 g mol^(-1) Then, number of moles HNO(3)=(68)/(63)mol = 1.079 mol Given, Density of solution = 1.504 g mL^(-1) Therefore, Volume of 100 g solution = (100)/(1.504)mL = 66.49 mL = 66.49xx10^(-3)L Molarity of solution = (1.079 mol)/(66.49xx10^(-3)L)-16.23 M
