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?
The average molecular speeds of the two gases are the same The total masses of the two gases are the same The partial pressures of the two gases are the same The average kinetic energy of the two gases are the same The molecular masses of the two gases are the same
5. The temperature of an ideal gas in a 5.0 L container was raised in temperature from 20.oC to 80.oC. If the initial pressure of the gas was 1200 mmHg, what was the final pressure of the gas?
1100 mmHg 1200 mmHg 1300 mmHg 1400 mmHg 1500 mmHg
