39. One mole of an ideal gas is expanded from a volume of 1.00 L to a volume of 10.00 L against a constant external pressure of 1.00 atm. Calculate the work. (1 L• atm = 101.3 J) (A) -456 J (B) -1010 J (C) -912 J (D) -2870 J

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
