You titrate a 85.00 mL sample of this solution with 3.550 M sodium hydroxide. It takes 67.50 mL of the sodium hydroxide to reach the endpoint. What is the concentration (in molarity) of the sulfuric acid in the bottle? Given:  

A 38-year-old woman is evaluated for 6 months of progressive dyspnea on exertion, orthopnea and 2+ pitting edema in both extremities.  She reports occasional “crushing-type” chest pain.  Past medical history is unremarkable.  She does not smoke cigarettes and rarely drinks alcohol.  There is no family history of heart disease. On physical examination she is afebrile.  Blood pressure is 140/90 mm Hg, pulse is 80 /min, and respiratory rate is 14/min.  Chest pain is not reproducible by palpation.  Crackles and rales are heard upon lung auscultation.  An S3 heart sound is easily appreciated by auscultation, and jugular venous distension is observed.  ECG shows sinus tachycardia and moderate left ventricular hypertrophy. 24. Which of the following findings will most likely be observed on this patient’s chest x-ray?
