Show hintHide hint
Think about the relationship between gas volume and number of particles.
Question 2.
How many liters does 1 mole of gas occupy at STP?
Show hintHide hint
Recall the standard measurement for gases.
3Question 3.
What does Avogadro's Law state?
- A. Equal volumes of gases have equal pressures.
- B. Equal volumes of all gases contain equal numbers of molecules at the same temperature and pressure.
- C. Gas volumes are not related to temperature.
Show hintHide hint
Remember the connection between gas volume and molecular count.
4Question 4.
True or False: At STP, 1 mole of gas occupies 22.4 liters.
- True
- False
Show hintHide hint
Think back to the definition of molar volume.
Question 5.
A researcher collects 33.6 liters of an unknown gas at STP. How many moles does the gas contain?
Show hintHide hint
Think about how the volume relates to the defined molar volume.
Question 6.
In a reaction, 3 moles of hydrogen gas are mixed with 1 mole of oxygen gas. How much volume does the hydrogen occupy at STP? How much water vapor will form?
Show hintHide hint
Consider the stoichiometry of the reaction and how it relates to volumes of gases.
