Ibuprofen (C13H18O2) is the active ingredient in many nonprescription pain relievers. Each tablet contains 200 mg of ibuprofen, and a typical adult dose is two tablets every six hours.Determine the molar mass of ibuprofen (show your work).Calculate the number of moles of ibuprofen in a single tablet (show your work).Calculate the number of moles of ibuprofen that an adult would have taken if she took four doses of ibuprofen in one day (show your work).. Sulfur dioxide gas (SO2) reacts with excessoxygen gas (O2) and excess liquid water (H2O) to formliquid sulfuric acid (H2SO4). In the laboratory, achemist carries out this reaction with 67.2 L of sulfur dioxide and gets250 g of sulfuric acid.Write a balancedequation for the reaction.Calculate thetheoretical yield of sulfuric acid.Calculate thepercent yield of the reaction.(One moleof any gas occupies 22.4 L under certain conditions of temperature andpressure. Assume those conditions for this question.)Answer:
