A sulphuric acid solution has pH = 3 . Its normality is

Calculate the mass percent (w//w) of sulphuric acid in a solution prepared by dissovles 4 g of sulphur trixoide in a 100ml of sulphuric acid solution containing 80 mass percent (w//w) of H_2SO_4 and having a density of 1.96 g/ml. (Molecular weight of H_2SO_4=98 gm ) Taken reaction SO_3+H_2OtoH_2SO_4

Molarity: A sample of commercial sulphuric acid is 98% H_(2) SO_(4) by mass and its specfic gravity is 1.84 . Caculate the molartiy of this sulburic acid solution. Strategy: The density of a solution (grams per milliliter) is numercially equal to its specific gravity. Thus, the density of the solution is 98% H_(2) SO_(4) by mass. Thus, every 100g of soultuon contains 98g of pure H_(2) SO_(4) . From the mass of H_(2) SO_(4) . we calculate its moles and from the density , we calculate its volume. Finally, we calculate molartity using its definition.
