1. A gas sample with a constant number of gas molecules and at a constant temperature has a volume of 5.0 L at 50 mmHg pressure. The volume of the container can be varied. What would the gas sample volume be (in Liters) if the pressure of the gas increased to 500 mmHg?
2. A gas sample with a constant number of gas molecules and at a constant temperature has a volume of 55.0 mL at 565 mmHg pressure. The volume of the container can be varied. What would the gas sample volume (in mL) be at a gas pressure of 250. mmHg? Round the answer to a whole number.
3. A gas sample containing a constant number of gas molecules has a volume of 2.70 L at a constant pressure and a temperature of 25.0o C. What would be the volume (in Liters) of this gas sample at 75.0o C? Round your answer to 3 sig fig
4. A gas sample containing a constant number of gas molecules has a volume of 1.50 L at a constant pressure and a temperature of 298 K. At what temperature would this gas sample be if the volume were changed to 0.500 L and the pressure remained unchanged? Keep the temperature in Kelvin and round to 3 sig fig.
5. A cylinder has a volume of 9.65 L. If the cylinder contains 3.03 mol of neon at 23o C, what is the pressure in the cylinder? Report your answer in atm and round to 3 sig fig.
6. What is the pressure of a 0.200-mol sample of radon if it occupies 5.00 L at 100o C? Report the pressure in units of atm, not mmHg and round to 3 sig fig.
7. An experiment requires 2.50 moles of carbon monoxide (CO) at 55o C and 1.50 atm. What is the volume of this sample? Calculate the volume in Liters and round to 3 sig fig.
8. What is the volume of 0.125 mol of hydrogen at 75o C and a pressure of 775 mmHg? solve for the volume in Liters and report your answer to 3 sig fig
9. A chemical reaction produces 125 mL of nitrogen at 26° C and 745 mmHg. How many moles are produced?
10. How many moles of helium will occupy 545 mL at 760 mmHg and 20°C? your answer should have 3 sig fig (since 20 + 273 will give a Temp to 3 sig fig)
11. How many grams of helium will occupy 545 mL at 1.00 atm and 293 K? Round your answer to 3 sig fig.
12. The maximum safe pressure that a certain 4.00L flask can hold is 3.50 atm. If the flask contains 0.410 mol of a gas, what is the maximum temperature in Celsius, to which this flask can be subjected? Report your answer to 3 sig fig, so the answer should be a whole number
13. What is the temperature in Celsius of 28.0g of nitrogen if it occupies 10.0 L at 755 mmHg? A whole number answer will result due to the 3 sig figs in calculations
