1. At 1.70 atm, a sample of gas takes up 4.25L. If the pressure in the gas is increased to
2.40 atm, what will the new volume be?
2. 30 L of a gas is at 725.0 mmHg pressure. What is its volume at standard pressure?
3. 4.35 L of a gas is at 1.16 atm. What pressure is obtained when the volume is 9.3 L?
4. A gas is collected and found to fill 4.73 L at 35.0°C. What will be its volume at standard
temperature?
5. 5.00 L of a gas is collected at 100 K and then allowed to expand to 50.0 L.
6. 3.00 L of a gas is collected at 35.0°C and 705.0 mmHg. What is the volume at STP?
7. A sample of dry gas weighing 3.1134 grams is found to occupy 3.650 L at 22.0°C and
740.0 mmHg. How many moles of the gas are present?
8. A sample of gas at an initial volume of 8.33 L, an initial pressure of 1.82 atm, and an
initial temperature of 286 K simultaneously changes its temperature to 355 K and its
volume to 5.72 L. What is the final pressure of the gas?
9. 500.0 liters of a gas in a flexible-walled container are prepared at 700.0 mmHg and
200.0 °C. The gas is placed into a tank under high pressure. When the tank cools to 20.0
°C, the pressure of the gas is 30.0 atm. What is the volume of the gas?
10. The pressure of a gas is reduced to 75% of its initial value and the volume is increased
by 40% of its initial value. Find the final temperature, given that the initial temperature
was −10 °C.
11. The pressure of 8.06 L of an ideal gas in a flexible container is decreased to one-third
of its original pressure, and its absolute temperature is decreased by one-half. What is the
final volume of the gas?
12. A gas occupies an 8.00 mL flexible-walled container. The pressure is doubled, the
absolute temperature is quadrupled, and 15% of the gas leaks out. What is the new
volume?
16. If 20 cc of ammonia gas diffuses in 45 seconds, how much volume of carbon dioxide
diffuse under similar time and condition? (density of NH 3 = 0.717 kg/m and density of CO 2
= 1.832 kg/m 3 )
