2. If you have a gas taking 14.0 L at 800. torr and 26oF, calculate the volume of the gas at 40oC and 2 atm.
4.13 L 16.34 L 8.27 L 5674 L 4.26 L

3. At 298oK, 800. torr, and 250. mL of gas has a mass of 4.62 grams. What is its molecular weight?
300 46 3.21 0.0107 429

4. A container contains 0.20 moles of O2 and 0.15 moles of H2. If the temperature of the container is 273 Kelvin, which is true?
