Question

Background The common laboratory acids such as H2SO, HCI, HNO3, and HC2H302 arrive in the teaching stockroom as very concentrated AQUEOUS solutions that we refer to as concentrated H2SO4(aq), concentrated HCl(aq), etc. You used con (concentrated) H2SO4(aq) as a catalyst in the preparation of aspirin. Calculate the molarity of con H2SO4(aq). Information on the container tells us that con H2SO4(aq) is 96.0% by mass H2SO4 and has a density of 1.84 g/ml. In carrying out the calculation, assume you are starting with 1.00 L of con H2SO4(aq). Follow the steps below to calculate the molarity of con H250. SHOW YOUR WORK a. What is the mass of 1.00 L of con H2SO4(aq)? b. How many grams of H2SO4 are in this 1.00 L of solution? How many moles of H2SO4 is this? C. Apply the definition of molarity to calculate the molarity of this con H2SO4 solution
