AB CHEMISTRY 1 | PRACTICE TEST SET #11
I. Problem Solving: Solve the following problems about Gas Laws
1. 400.0 mL of a gas are under a pressure of 800.0 mmHg. What would the final volume of
the gas be at a pressure of 1000.0 torr?
2. A sample of helium has a volume of 500 mL at a temperature of 18°C. When the
temperature is increased to 23°C, what is the final volume of the helium?
3. The initial temperature of a 1.00 L sample of argon is 20°C. The pressure is decreased
from 700 mm Hg to 320 mm Hg and the volume increases to 2.14 L. What was the
change in temperature of the argon?
4. A sample of sulfur dioxide occupies a volume of 650 mL at 50°C and 710 mmHg. What
volume will the sulfur dioxide occupy at STP?
5. A sample of hydrogen has an initial temperature of 49°C. When the temperature is
lowered to 12°C, the volume of hydrogen becomes 3 L. What was the initial volume of
the hydrogen?
6. 500.0 mL of a gas is collected at 745.0 mmHg. What will the volume at standard
pressure?
7. A 20 L cylinder containing 6.00 atm of gas at 28°C. What would the pressure of the gas
be if the gas was heated to 75°C?
8. Consider a container with a volume of 22.4 L filled with a gas at 1.00 atm at 273 K. What
will be the new pressure if the temperature increases to 298 K?
9. How many moles of gas will a 1310 mL flask hold at 36.0 deg. C and a pressure of 93.4
kPa?
10. What is the gas pressure within a cylinder if there is 6.0g of CO2 gas in a 10 L cylinder
at 24
o
C inside it. (C = 12 g/mol and O = 16 g/mol)
11. A 23.8 L of balloons is filled with 88g CO
2
at 15
o
C. What is the pressure of the inside the
balloon?
12. Suppose you have a 1.5 L flask containing 6 grams of CO
2
and 3 g of O
2
at 26
o
C. Find
the partial pressure and the total pressure in the flask?
13. 11 g of nitrogen gas and 12 g of helium gas are placed together in a 10 L container at
25°C. Calculate the partial pressure of each gas and the total pressure of the gas
mixture.
