CHAPTER 5 MAKE UP HOMEWORK 1. A 48.3 mL sample of gas in cylinder was warmed from 22 o C to 87 o C. What is its volume at the final temperature? 2. What is the volume occupied by 0.118 mol of helium gas at a pressure of 0.97 atm and a temperature of 305 K? 3. An automobile tire had a maximum rating of 38.0 psi (gauge pressure). The tire is inflated (while cold) to a volume of 11.8 L and a gauge pressure of 36.0 psi at a temperature of 12.0 o C. While driving on a hot day, the tire warms to 65.0 o C and it volume expands to 12.2 L. Does the pressure in the tire exceed its maximum rating? (Note: the gauge pressure is the difference between the total pressure and atmospheric pressure. In this case, assume that atmospheric pressure is 14.7 psi.) 4. A sample of gas has a mass of 38.8 mg. Its volume is 224 mL at a temperature of 55 o C and a pressure of 886 torr. Find the molar mass of the gas. 5. A gas mixture contains 1.25 g N
