37. Which of the following compounds has the lowest boiling point? (A) CH3OCH3 (B) CH3CH2CH3 (C) CH3COOH (D) All the boiling points are about the same since the molar masses of the three compounds are essentially equal.

5. One milliliter (1.00 mL) of acid taken from a lead storage battery is pipetted into a flask. Water and phenolphthalein indicator are added, and the solution is titrated with 0.50 M NaOH until a pink color appears; 12.0 mL are required. The number of grams of H2SO4 (formula weight = 98) present in one liter of the battery acid is (to within 5%): (A) 240 (B) 290 (C) 480 (D) 580
