You can ume you have a total m of 100 grams. There would be 70.5 grams of nitric acid and 29.5 grams of water. The volume of the solution would be (100 grams)*(1ml/1.4134g) which is 70.75 ml of solution. That is equal to .7075 liters. Then convert the 70.5 grams of nitric acid to moles by dividing by molecular weight, which will give you 1.12 moles nitric acid. Molarity is moles per liter, which is 1.12/.7075, which is 1.58 M.
