(1.6(a)A7) (2 points) 5. An automobile tire was inated to a (gauge) pressure of 24 lbs/in2 (1 atm = 14.7 lbs/in2 ) on a winters day when the temperature was -5 C. Assuming no leaks have occurred and that the volume is constant, what is the (gauge) pressure (in lbs/in2 ), on a subsequent summers day when the temperature is 35 C? (e1.8(a)A7) (4 points) 6. In an attempt to determine an accurate value of the gas constant, R (in J), a student heated a 20.000 L container lled with 0.25132 g of helium gas to 500. C and measured the pressure as 206.402 cm of water in a manometer at 25 C. Calculate the value of R from these data. (The density of water at 25 C is 0.99707 g/cc.) (e1.10(a)A7) (3 points) 7. At 500. C and 699 Torr, the mass density of sulfur vapor is 3.71 g/L. What is the molecular formula of sulfur under these conditions?
